I'd bid 1h, 1h shouldn't promise a 5 card suit here and I have a good hand for a 1nt or 2c rebid by pd. I want to let him know that I have some values so we can fight a partscore. They will be in 2 spades soon and I want to know if we can compete to 3c or 3h inmediately. I wouldn't like thinking about bidding this hand later if I can bid 1h now. I couldn't agree more, but the same holds true over an opening of 1M, if partner openend 1Sp I wanna bid 1NT over opp t/o dbl, for exactly the same reasons, so that transfer idea doesn't appeal to me
