Normally with a balanced hand people bid 1NT and have some mechanism for checking back for support or four of the other major.

Each of your options is commonly played somewhere.

This is very interesting; I play strong NT in 3rd at teams (and my partner is thinking about switching to strong throughout at teams) and I have never really thought about the implications of a 1NT rebid showing a weak NT as opposed to a strong NT.
Also, sorry to go off-topic, but I do not play support doubles, and I wonder if they are sensible when playing a strong NT?

Because of, or in spite of, their opening 1m agreements they feel an urgency to show an unbalanced vs. balanced hand. We don't feel that immediate urgency, and don't really know how many other continuations are affected by that style. We just know that we are content that 1m-1H-1S might or might not be balanced; and it IS forcing upon responder who actually had a response to begin with ---but passable if responder doesn't care that Opener might have a balanced 19 count.

I don't quite follow this so-called edge in the final sentence. I would have thought that 2C is easier to find after a 1M rebid promises a genuine 1C opener. Not that that is the real benefit of the method, in my view, although now that you bring the subject up I suppose it would add to it. A more pronounced edge is LHO's doubt about the safety of leading Spades v 1NT. But even that isn't really the main point.

IMP v MP may also have an influence. Anyway, personally I prefer strong 1N with transfer walsh, and accept the transfer with a weak 1N, but I had to vote according to the constraints of the imposed system, and this is a Natural Systems forum.

I would really hate having to bid 1NT with 4S and without a stopper in the other minor, wrongsiding 1Nt or 3Nt for little benefit is really not my style, on the other side bidding 1S with a flatish hand and nice stoppers in the unbid suit is also weak bridge IMO.
For instance, he doesn't like being used as a human shield when we're being shot at.
I happen to think it's a very noble way to meet one's maker, especially for a guy like him.
Bottom line is we never let that difference of opinion interfere with anything."

Not internationally.
All the good players in England that I can think of, who play a relevant system*, always rebid 1NT with a balanced hand and use 1S for an unbalanced hand.
It's almost universal in Norway to rebid 1S whenever you have 4 (although some of the top players don't)
From what I can tell from reading BW / watching vugraph, there isn't a US standard. There might be a geography effect in the US, but I don't know enough about where players are from.

The "edge" you have because they can't play in 2C is negative: it's much easier to play in clubs if 1C - 1suit - 1S shows an unbalanced hand, because responder knows you have real clubs.

Playing weak NT, support doubles are not sensible (double is needed to cover some strong NT type hands).

It's not necessary to be in a very experienced partnership. You just need to have discussed your continuations after a 1NT rebid. The main downside of rebidding 1NT is when Responder is 4-4 in the majors and not strong enough to bid on over 1NT. (This is a less frequent loss playing weak NT; playing weak NT opening Helene is right that it's much more important to be able to show your hand type (shape and extra values) immediately.)
The downside of bidding 1♠ with the balanced hands is that it makes is harder to find he length of a club fit. I remember watching a USA pair playing in the Bermuda Bowl a few years ago. They bid 1♣-1♥-1♠-3♣-Pass and they were playing in a 3-4 ♣ fit with two balanced hands.
Suppose that the auction goes 1♣-1♥-1♠-2♦ (4th suit forcing). If a 2♥ bid now by Opener can be 4=3=3=3, 4=3=2=4, 4=3=1=5 or 4=2=2=5 (or even 4=2=3=4 with no ♦ stop), you've got a lot to unscramble.

Playing strong NT, it is closer, but I am still firmly in the camp that rebids 1NT.
- On unbalanced hands, I am much better placed, both in terms of reaching 2C/3C when it is right, and 4SF auctions as described by jallerton.
- On balanced hands with four spades, there are swings and roundabouts. Rebidding 1NT limits my hand better and makes it easier to reach 2H.
- On balanced hands without four spades, the losses are small - eg 4S5H invite is likely to get higher in my style.
I've intentionally ignored information leakage to defenders because that is very hard to quantify.
After 1m:1H, 1NT, I think it is important to have a way to show 5H4S weak, although most pairs seem not to now two-way checkback has superceded simple checkback.
If you open 1C on all weak NTs, I think it is clear to rebid 1NT on these hands; I would hate to play that 1C:1H, 1S could be a 4-3-4-2 12-count or a 4-1-3-5 12-count.
