Mr Track,
I have not thrown the Revmaster. I have seen a few thrown around here, and it seems like most of the guys scoring with them are using them on sport conditions that have short oil----or extreme wet---dry, playing the dry ofcourse.
With the dynamics of this ball I agree with the 5x3.5. If it ends up rolling a little too soon for you, a splash of delayed reaction should help.
NOW, with that said, the Thrash was an amazing ball for me. I consider myself a tweener, high speed-----with a rev rate of only around 320, 350 on the high end. The I had my Thrash drilled with a 4 inch pin, and it was a pretty smooth reaction throughout the lane, but when it hit dry, I turned sharply. SO the same drill 5x3.5 should work well with that ball as well. The Thrash was probably (along with the Crunch) one of the most underappreactiated balls of the year last year.
You can pick up either of these pretty cheap now, so flip a coin and run with it. I am considering drilling a Revmaster for myself this summer, that way during the summer league I am not beating my other stuff to death.
