With the advent of Laser Rangefinders speed doesn't mean too much to me. Unless you shoot a lot of 3D's where catching a line once in a while helps your score, then a smooth quiet shooting bow shooting 400gr arrows in the 250-260 range is a very lethal combination. As for being slow, My recurve is shooting 165fps....

A true sportsman counts his achievements in proportion to the effort involved and fairness of the sport. - S. Pope
