RE: conviece me which brand to buy
as previously said, go buy the best feeling bow. if possible, get 3' or so from the target (extend your bow arm and take 3 steps back from the target) keep your eyes closed, and let the dealer hand you bows and not tell you which is which.
That being said, I shoot a Hoyt Protec with Spiral cams.
