What equipment are you currently throwing? Pearl? Solid? Particle? Is it dull or shiny? Also, how do you throw the ball? Do you come up the back of the ball more and get end-over-end roll, or do you tend to spin it more and get more sideways rotation? You also mentioned lower rev rate, but said nothing about your ball speed. What part of the lane are you playing currently? Before getting another ball, you may be able to kick out the 10 with just some small changes to your ball surface or your release or how you are playing the lanes.
