Urethane offers good versatility, but some of the stuff that's out there today is a little bit weak in the hit department. If you're planning on using it in order to stay in control on tougher patterns, you're probably going to like what you see. Don't, however, expect the ball to be a go-to scoring option. From what I've seen, most of the newer urethane balls lack the punch needed to provide that option.
