I have not personally thrown the SCB, but my best friend rolls with one regularly, and he raves about it. I have seen it in action, and it is just as Mumzie says,..."will move when nothing else can". The ball, from my observations, is extremely predictable, and has devastating carry. My partner even uses it when there is no heavy oil available!! Of course, he has good speed and is a cranker. This ball goes moderately long and then just rolls up with a very hard arc. I've seen him use it on heavy oil, medium oil, and he has actually tried it on lite oil as well...( with ugly results) I might add.
He has his ball laid out for early roll. Pin high, about half an inch higher than the ring finger, and cg kicked about .75 of an inch. This set up is shifted to the right of the ring by about an inch, also. I have seen this ball devastate the pocket, and I have seen him win massive money pot games, with this ball continually riding high on the head-pin with strike after strike! The ball just plain carries well. It'll give you constant "peek-a-boo" 7-10 leaves, but it somehow always kicks them out. (Not on lite oil, though)
Definitely a "must have" piece to save you when you get in trouble. I know I want one!
