Careful with the Razyr; it was kind of an all-or-nothing type of ball. Basically, Hammer put a very aggressive reactive shell on a pancake block. I had one during my two-handed bowling days, and the ball was as strong or stronger off of the friction than anything I had in the bag at that time; however, when I threw it one-handed, it was sixty feet of skid. A friend of mine has a ton of revs, and that ball was very sharp off of friction for him too. So, if you are a medium to lower rev player, the Razyr could be okay for big-time burn. If you have a lot of hand, I think you'd find it way too strong down the lane.
