How heavy is your Beat'n, JRC? That's a pretty new ball; are you sure you need a heavier one? You might want to focus on slowing it down, becoming more consistent, and mastering basics. A coach is a great thing - I hired my coach about a year ago and he has brought me to new levels of bowling I never knew before. I think that's a good idea.
I'm 14. When I signed onto ballreivews (about 8 months ago), I thought it was all about my equipment, but I quickly learned that it wasn't. There's much more to be learned about technique than there is to learn about technology. It's interesting and all, but you can only go so far with a new ball. I think you can go a lot further with what you own now that even you think you can, trust me. Unless you're flat out chucking your No Mercy, you might not need to change weight. I also feel that if you are using a No Mercy for day to day leagues, you don't have "high revs," because that ball is too strong. Once again, JRC, you should learn about becoming consistent with your revs and speed rather than buying a stronger ball, because you can only get so far. Look into a weaker ball with a symmetrical core (if anything), heavier if need be.
I hope this helps. Consider a coach - and remember that nothing will beat practice.
