I think this is totally a personal physique, form, and preference type of deal. For me, I'm 5'10" with shorter arms, larger chest, and I like full draw with good alignment. I draw a little iver 27.5". For me, my 60" Recurve gives me fits in the tree if the treestand is 15-17ft up and deer are less than 12 yards or so. I've tried lots of positions and its tricky, too tricky to worry about when it's go time... The 60" works fine with less angle, lower treestand, longer shots, etc.. I tend to have string interference with chest or limb/string interference with leg. I switched to a Black Widow 54" KB and it's perfect for me. No more issues with interference at all and even better it's not on my mind as a distraction... I can focus on the deer and make it happen. So, practice and test for yourself what works, it may be different than others...
