I understand what you are saying as I originally began shooting my longbow with my high wrist recurve grip with rather poor results. :D In fact my recurve bow has a very high grip that "forces" you into keeping your wrist etc. in a line. Perfect. I found though that in switching to the longbow, the longbow grips of old/Howard Hill style ("D" shape) became part of their challenge/appeal for me. You might give yourself some time with it unless you really do want to keep switching back and forth between the longbow and the recurve. I haven't been doing that so maybe that would present some problems. Just a thought.
