Well, I am short of stature, so I don't get along well with really long bows. My 58" Kanati is a hybrid bow that fits me just perfect. It is smooth and has no hand shock. The design is everything. True, it is only 46# at my 28" draw, but it shoots hard and fast, so I don't need anything more. It puts arrows where I want them to go, which is the most important thing. I can easily push/pull string it. Anything over 62" and I need a stringer.
I have shot Kanatis at 52# and they too were smooth and shock free. My 62" Mahaska is also smooth, but it will thump you pretty good unless you use a skinny string.
Find something that fits your hand, draws smoothly, has no hand shock, and hits where you point it. Then don't worry about the length.
