Hey all.  I was able to get a Fast beyond cheap but have also been looking at a Dark Star.  I see the ball specs are very similar between the 2.  The Fast I have drilled 60x4x40 and it is a very strong ball!  Stronger than i thought it would be.  I am looking for something to throw on an older wood surface and the Fast definately isn't it, surface on it right now is 4000 AB with a light coat of polish.  Can I expect the same out of the Dark Star?  Once the Fast finds friction it's all over.

BTW: I come up the back of it more than the side, rev rate around 400-425.  Speed at the pins 16.5-17 PAP 5 over 3/8 up righty.
