After throwing this ball for a few weeks, all I can say is WOW. I think that this ball provides a more angular backend reaction with continuation than I've ever seen in my life. Unfortunately, in the house I bowl in right now, balls that are angular are bad news because you leave way too many 8 and 9 pins. This ball does get back from places that most bowling equipment doesn't, so I can't fault C300 for false advertising. This ball is definitely a tweener's dream and will be a big part of my arsenal for the forseeable future.
I'm definitely going to post a review when I get the chance to throw it on some PBA Experience League shots (that aren't Cheetah) and in a few other bowling centers. But I definitely like what I see so far.
