I'm currently using a columbia particle scout. The ball is ok, but I wanted something that hits a lot more. My friends have oracle, xxx extreme, and track, and their balls hit a lot harder then mine. Depending on your revs, etc., you would get your ball around this. I was wondering how I would measure more revs. I currently bowl a 150-160. My ball tends to hit at the end, and I bowl on medium to heavy oil. Thanks!!
