My family has similar problems, we all have draw lengths in excess of 30″.
When my dad switched he ordered a bow from Steve Turay at I believe Great Northern Longbow, Steve made a reverse handle that he liked a lot. Since then we’ve gotten into making our own, and at 6’9″ I shoot a 72″ longbow with no problems.
I guess I’d suggest looking for a reverse handle, you make be able to avoid the stacking you’re currently experiencing or look for a longer long bow.
