Without prior discussion, 1S.
We schwitched to the style that makes a 1NT rebid,
and I think showing your shape as fast as possible
is important, but you need to discuss this beforehand.
As it is, overall I dont think it matters a lot.
With kind regards

PS: 2H is not an option for me, I only raise with 3 card
support, if I have a single, i.e. a 5431 shape.

o don't bypass a spade suit
or
o will rebid 1NT with a balanced hand and that as a consequence 1♠ is always unbalanced.
or play that you will:
o always show three card support
o show three card support when the hand is unbalanced
o show three card support when you don't have 4 spades
o show three card support when you can't rebid at the 1 level
o only show three card support when you are stuck for a rebid (pretty much impossible after 1♦-1♥, but certainly possible after 1♣-1♠)
o never show three card support. Supporting always shows 4 cards.
Don't decide on a case by case basis what you will bid. Of course, exceptions are allowed but only when you know (rather than: think) that your hand is an exception to the rules.

I was sitting South and rebid 1NT which was passed out. -150.
When I first started posting on this forum I played Acol weak no trump. Way back then in 2005 it would not have occurred to me to have rebid anything but 1♠. Then I read this post:

Check-back? I had heard of it but wtp rebidding 1♠. xyz? Whats that?
In my desire to improve, I learnt 5 card majors strong notrump and the various ways of playing check-back, albeit recognising that 4-4 major fits can be lost by playing this way. A rationalisation was that you would be no worse off than with acol 12-14 when you has a weakish hand with a 4-4 spade fit opposite a 12-14 no trump. Against that a 15-17 no trump opposite 5-7 would miss a 4-4 major suit fit, and Acol weak no trump would not.
New resolution: I will always rebid 1♠ unless 4333 Justin-like lol!. Comparing the responses in this post with the 2005 posts, it is interesting to see that opinions are fairly evenly divided and that Justin, Mike on one side and Hog on the other have not changed their views.

If you and your partner agree that after 1 Diamond 1 Heart your first priority is to show strength and shape with 1 NT, your partner should have known that 1 NT is often the wrong strain. You have at most 8 cards in the minors (44 or 53), else you had no 1 NT rebid. So, you must hold at least 5 card in the majors, so a fit is more then possible. The worst case is a 3244 or 3253 (not unlikely of course), where you have to play a 5-2 fit.
So partner must have a tool do ask about your hand without leaving the 2. level. Without all this, KISS, bid 1 Spade like most do.

As an adherent of the 1NT > 1S on balanced hands style, you will note that I did not rebid 1NT but 2♥. Responder has the hand type I was worried about: weak hand, mediocre (and unrebiddable) hearts, and a potential problem in clubs. It turns out the clubs are worth 3 tricks more on the defense vs. notrump, so the difference is down 3 vs. down 1 (hearts are a level higher). So I think this is less about your system and more about a misapplication of judgement.
Re: hearts vs. spades, both strains take only 7 tricks on best defense. Partner did not have a third club to make use of the ruffing value, and yet either major still plays better than notrump. One advantage of spades is that the North hand can pass 1♠. But then the East hand has a clear reopening double and then they can find the E/W par of 2♣ making 2. -50 in 2♥ or 2♠ seems to be practical par at IMPs.

You may want to play 1D 2H as 5H+4S and weaker than invitation if you play a style to rebid 1NT regardless of spade holdings.

A comparison hand: http://thegargoylechronicles.blogspot.com/...5.html#comments
The author strongly prefers correcting to 2M with a much worse 5cM AND with the possibility that partner has a singleton spade.
BTW, that blog is the bomb.

(1) After 1♦-1♥-1♠, 2♦ is game force. You have space to relay out opener's entire shape, even if 4243/4324 hands are permitted. For example, you could play opener's 2♥ rebid is balanced or three suited and use symmetric relay the rest of the way. Note that symmetric relay is incredibly accurate in unobstructed game-going auctions -- you get opener's entire shape and general strength before 3NT and can find all the controls at a reasonable level too. Considering this, I very much doubt that excluding the two hand types above (4243/4324) is a huge boon to anyone's slam bidding. Most partnerships could benefit far more in the slam zone by using more carefully constructed followups to the game forcing call.
(2) What about game invites? Again using XYZ, you have two paths to 2NT. You can bid 2NT directly to show a hand that would bid 2NT even if 1♠ is unbalanced (i.e. no real fit). You can bid 2♣ followed by 2NT to show a hand with a mild diamond fit, where you would show a diamond invite provided opener had a shapely hand with 5+♦. This gets you to the right partial, finds 5♦ when it's a better game, etc. Most pairs who use XYZ here basically have more sequences than they know what to do with anyway (and either leave a lot of sequence undiscussed or assign them meanings that almost never come up).
(3) What about partials? Well, 1♦-1♥-1♠ does not promise five diamonds in any case because of the possible 4-1-4-4 hand. And it does promise four diamonds (assuming you open a club with 4333, as is the popular style). So you're not losing much here either.
The "information to the opponents" thing is mostly an illusion too. Sure, there are auctions where bypassing 1♠ hides opener's four-card spade suit from the opposition. But there are also auctions where responder has to show a four-card spade suit that he could've hidden on the way to game, because opener might still have a fit. For example, say responder has four spades and opener doesn't. Up-the-line bidding you get 1♦-1♥-1NT-3NT and no one knows about responder's spades. Bypassing you get 1♦-1♥-1NT and now responder has to bid checkback to see if opener has four spades, and you end up handing a huge amount of information to the defense (often not just that responder has four spades and opener doesn't, but frequently also extra information about opener's heart and/or diamond length). So you're just trading one auction being more informative for another auction being less so.
On the other hand, bidding up the line has advantages. You find your spade fits when responder is fairly weak (could even be a game if responder has shape). You can play 1♠ if responder has garbage. You can decide who declares in notrump based on the club situation (this can easily be a game swing).

The last point (right-siding the notrump) can be addressed by raising to 2♥ instead of rebidding 1NT on hands with clearly anti-positional holdings in the 4th suit. The biggest problem with a balanced spade rebid + XYZ structure is that you cannot play in 2♣ after opener starts with 1♣ -- responder can have a hand that is a clear weak preference to clubs if 1♠ promises an unbalanced hand. I would never play XYZ over a 1♣ opening with the unbalanced spade style. Obviously if you do play the (standard) balanced spade style, XYZ + symmetric relays have much to recommend them, but that is a significant amount of complexity that I feel most partnerships don't have the inclination to adopt.

Sure, but we were talking about 1♦ openings. The situation after 1♣ opening is somewhat different. First, XYZ is worse because it eliminates the ability to sign off in 2♣ (much more frequently desirable when partner opened 1♣ rather than 1♦). Second, opener could easily have three clubs for 1♣...1♠ (three-card diamond suit would be 4432 only, which raises hearts) which adds an extra hand type and makes raising clubs more awkward.
On the other hand, playing 1♠ as an unbalanced rebid combined with XYZ is really a horrible method, since now the odds of wanting to play 2♣ go way up (you know partner has a real suit).

I didn't realize that we were only talking about the 1♦ - 1♥ - 1♠ auction. Most people don't really want to differentiate between that auction and 1♣ - 1♥ - 1♠, even if it would be technically correct to do so. (And yes, I agree with all your technical points.)
From a practical standpoint, I feel you're making an unfair comparison between unbalanced spade + simple followups vs. balanced spade + XYZ + symmetric relays. I believe the majority of standard system partnerships are not interested in having different methods over 1♣ and 1♦, or into complicated 3rd-round followups such as a symmetric relay after the XYZ 2♦. That obviously doesn't apply to some of the regulars on these Forums, of course.

In reality I'm not even a big fan of XYZ; I'm just mentioning it as evidence that you have so much space to work out opener's hand in these auctions, that you shouldn't really suffer in game sequences from including balanced hands in the 1♠ rebid. Thus the concern about whether to bid 1♠/1NT shouldn't really be about "getting partner the information he needs to decide about game and slam" because there is plenty of room to make those decisions accurately even when we include the balanced hands in the 1♠ rebid. The concern should be more about "how do we get to better partials when responder is weak" and "how do we make sure that 3NT is declared from the proper side when it is our best contract." Bidding up the line is a clear winner in both those scenarios.

Bidding up the line is a clear winner in both those scenarios.
Adam makes a number of good points, but, as is often the case with proponents of a particular style (I include myself in this by the way) omits matters that weaken his case and overstate matters that strengthen his case.
Thus the reference to playing symmetric relay. I have never played with and don't expect to ever play with anyone who uses symmetric relay, so I find it ridiculous, to argue in a General Bridge Discussion forum, that up the line bidding works just fine, thank you, if we all play symmetric relay.
I appreciate that Adam has recognized this point.
As for finding the right partial, Adam overlooks the worst dilemma for the weak responding hand.... whether to take a preference to 2minor or rebid 1N.
Admittedly, the dilemma is far worse after a 1♣ opening, using up the line, than it is over 1♦, but as Eugene pointed out and Adam conceded (I think) few partnerships will go so far as to adopt different styles over 1♣ and 1♦, regardless of the theoretical merits of doing so.
And thus any discussion of up the line, even after a 1♦ opening, must deal with responder holding, say, xxx KQxx Jxx Jxx and hearing opener rebid 1♠.
If we have to rebid 1N with this hand, we deserve to catch partner with some 4=2=5=2 or 4=2=2=5, depending on the opening call. Now, playing 1N rebid on all balanced hands, responder knows not to rebid 1N over 1♠...if opener opened 1♣. I admit that if opener bid 1♦, the odds are not so clear... but 4=3=5=1/4=1=5=3 and all the 4=6 hands add up, frequency wise, to a far higher likelihood than precisely 4=1=4=4, so at imps there is much to be said for 2♦ anyway.
Also, as someone who has played relay, but a different version than the one suggested by Adam, I found that eliminating the balanced holdings from the 1♠ rebid actually made the relays more effective. The hand-types can be refined at a lower level: relays should be designed so that the most common shapes are shown cheaply, while the less-frequent distributional hands are described with more expensive, in terms of bidding space, responses. Relay methods frequently encounter auctions in which relayer has to break the relay because he cannot risk an inconvenient answer as the level increases, so making the initial shape relay more efficient, by reducing the possible patterns, is an important tweak.
Of course, the trade off is that the hand patterns contained in the 1N rebid are increased, but they are still relatively few, thus the cost to a relay method of rebidding 1N on all balanced hands is less than the cost, to a similar relay method, of including balanced hands in the very large range of holdings possible following 1♠.
Frankly, my view is that this debate is akin to the discussions about whether opener should rebid 1N in auctions such as 1♥ 1♠ with holdings such as x AQJxx KQx Jxxx....where I, as a traditionalist, rebid 2♣ and some modernists choose 1N.
There are valid arguments on both sides and personal preferences/personal experiences/ and partnership harmony issues are probably more relevant than trying to determine, in any absolute sense, which approach is the better.

Maybe this is a continent thing, but here, many play different sets of responses to 1♣ and 1♦, for example transfer responses or 1♦ negative. Maybe related to the popular treatment that 1♣ can be a doubleton. So I would consider the two minor suit openings in isolation,

Pass wtp? But even if 1♠ is forcing (or we have a similar 9-count), I think 1NT is fine with a jack in the unbid minor. With xxx in the unbid minor, bid 2 of opener's minor. Even if the opening suit is clubs, partner should have four of them as he probably rebids 1NT with 4333 although he would rebid 1♠ with most 4234.
That said I like to rebid 1NT opposite an unpassed partner as it makes it easier for him to find out what I have if he is slamish. I really hate auctions starting
1♣-1♥
1♠-2♦
2♠
and responder still doesn't have a clue what opener has. Sure, elaborate FSF agreements, or maybe something with T-Walsh and/or XYZ, can solve the problem, but with most partner's my agreements don't go further than whether FSF is GF or not.

Rebidding 1NT just seems to make everything simpler. You know immediately which hand is in charge (unbalanced hands tell, balanced hands listen), responder can give preference on a doubleton when he so desires, and opener's third bid (especially over 4SF) is much better defined.
Of course, responder should have a way to show 5H4S NF over the 1NT rebid (but *not* over the 1m opener, where there is a case for a 2H bid to show 5-4 majors with five *spades*).
