I have a old 60" sears recurve up in the rafters that I shot four years before I even knew my draw length or what stack was but in hind sight it had a lot of finger pinch Im sure a 62" would work , Mike I appreciate the offer but still tossing ideas a round , part of the problem with starting a new design is the $$ to get to where you want, I would probably be smarter just to make more changes in the FH design I all ready have a lot of $$ invested and if I add addtional reflex & different riser I would have a pretty good guess at the stack & glass or carbon combos , if there was a proven recurve design that drew stack free @31 60" where there was data for stack etc , I might give it a go but I havent found any !
