FWIW, I got the opportunity to throw my Twisted side-by-side with my Zone Classic last night. The Classic is drilled with the pin 4 1/2" from the PAP, slightly above the fingers, and a 75-degree LL angle. The Twisted has the pin 4 3/4" from PAP, with a 45-degree LL angle. Both balls are in box finish. I used the two on a freshly stripped and oiled house shot.
The Classic started up several feet sooner than the Twisted, and went into a moderate arc at the break. In contrast, the Twisted looked much cleaner in front, but when it turned over, it had a harder arc (not quite a flip). While I had a good look with the Classic, I felt that the Twisted did a better job of opening up the lane; it seemed to handle the oil better than the Classic, even as the oil pushed down the lane. The Twisted was about three or four boards stronger overall.
Hope this helps.
