What are you intending to use the bow for? Only for hunting? Then it'll be fine. If you intend to it to spend time on the 3D course, you want a bow that won't beat you to death before day's end. One that's not so susceptable to muscle twitches. A hefty bow is much less tiring to shoot in tournament, and is much easier to shoot with CONSISTENT accuracy than a light one.

People can shoot light bows etremely well, until fatigue starts setting in. A tired shooter will shoot better with a bow that's got some weight to it.
