Speed is a really great asset. I try to get all I can out of my bow. However, speed usually aquired compromising forgivness. I like a forgiving, shootable bow. The really fast bows have really short brace heights, thus making them less forgiving. So basically anyone with less than perfect form (which is most of us) will hit the wrong spot at 320-350 feet per second. But like anything, " It' s great if you like it" .
