Has another got a chance to try it out and how this one is compared to some of the other pearl balls Ebonite has? I may go to the pro shop this week to order this one or Track's 505C since I don't have a medium oil ball under my Power Machine (need more of a control ball for tournaments). I did notice that it has a high differential so I didn't want something to dublicate my Power Machine even though it has the NVD coverstock (which I've had tons of success with).
