shoot diff lengths of the bow you want and then decide. my CM crusader is 62" 65#@28 I draw 29.5. I have shot LBR's 68" CM crusader approx same weight, it FEELS like pulling a childrens bow. I like the feel of the tension when shooting my bow. BUT I have a 64" 60#@28 CM crusader takedown on order. It boils down to personal pref. as stated above once you reach the 55#@28 mark going any higher the benfits begin to diminish. At least that is what the formulas I have viewed by other more mathematically inclined individuals have shown.
