Most bowhunters will tell you the same thing. You have to make that decision on your own. Each of us prefer different things in our bow. I prefer a light bow. I have a friend who likes to have a heavy bow. Do you want speed or accuracy or both. The best thing for you to do (I would be remiss if I didn't say almost anyone on here will tell you the same thing) go to your local proshop and get them to let you try shooting a number of different bows. Get the feel for it and make an educated decision.

Good luck.
