I prefer something around 36in AtoA howeverthe three bows Ihunt with now are 33 1/2, 34 and 36in, and all are just fine at 31-32in draw lengths. I think the riser design has something to do with it. For instance, I don't want a 37 (and up) inch AtoA in a parallel limb bow....too much riser for me.[:'(]
