Hey i am looking for one more ball to add this season..... So far i am rolling an ANARCHY, PERFECT RIVAL, and SD73 CLASSIC, I bowl in 2 different leagues, and also collegiately. I looking for something that will give me more hook on heavy oil sport patterns. I cannot decide between the INVASION or to wait for the MARVEL. I read the specs on both and they seem pretty similar. The INVASION will give me more back-end, but the MARVEL could be smoother and will a little less hook. Any thoughts would be great!!!! THANKS
