Depends a bit on how you play the 2/1 bid in comp. I'll assume the 2/1 bid = 10+ points, 1RF, does *not* promise a rebid, which I think is standard.
These are mostly "strong GF hand", "uncertain about strain, might want to play 3nt".
So I would think:
- strong bal/semi-balanced, no spade stopper, fewer than 3 hearts
- strong diamond one-suiter, no spade stop
- strong w/ both minors
- a few hands too strong for 4h, not a spade splinter
On the second hand there are probably more hands with some diamond support but without a spade stop, since you don't necessarily want to bypass 3nt with 4d like you can when responder's suit is hearts. But on the other hand, you *remove* the strong heart one suiters, since you now can jump to 3h, forcing.
