well If you are considering Hammer, since i saw you have a Black Widow, I would say go with a Hawgzilla for your heavy ball, I have seen a Infinite One in action and I believe that it ins't really a ball for heavy, the Zilla has more on it in that area, and my friends lost some its reaction fairly quick which wasn't very cool, he maintains his balls darn good to. Just my @ cents, because I myself see that you are lacking in the heavy oil department.

I thought my Hammers hit hard, until I whipped a LM/L ball into the pocket. WOW!
