I echo Charlest's comments; the Dyno guys on this website are very good, especially since one of them is Phil Cardinale, the owner, himself!
However, I will say that I have a friend that is on staff with Dynothane, and the Centrifugal Mass seems to give him a more angular breakpoint than almost all of his other Dynothane equipment, and the ball carries nearly as well as his favorite Dynothane offering, the original (Burgandy) Energy. Obviously, the angular breakpoint has a lot to do with the way he drilled the ball.
The Centrifugal Mass, being a dull solid/pearl combo, would likely require polishing and perhaps a weaker drilling to give you a ball for medium conditions. I would suggest going with an Energy if you're looking for the second ball in a two-ball arsenal.
HOWEVER...if you'd like to try another Track ball...there are several to choose from that would fit what you're looking for. I'd take a long look at some of the balls that Track has come out with in the last year, especially the Xception and the Xception 5.0. They would give you added length and strong backends when your GP2 is hooking too early, with the 5.0 being an earlier-hooking ball than the regular Xception.
You might want to take a look at the Arsenal Angular as well, as that would give you good length through broken-down heads with a strong move at the breakpoint.
Whichever company you choose...good luck with your bowling! Be sure to let us know if there's anything we can do to help you!
