This is my first review, so I'll try and be as accurate as possible. Read my profile for stats. I bought this ball in Sept. 2000. I ordered it with a long, 4-5" pin to Cg. I had it drilled 5x5, with the pin just above the ring finger, and the Cg just left of center. Lane conditions: a WALL just about everywhere that I bowl. I usually play 12-15 at the arrows, out to anywhere outside of 10. Swing any ball outside of 10 and it'll charge back to the pocket. Anyway, this ball reacted very well for a few months. Lots of high scores, the ball was easy to flip, and great carry. I used it a lot, always cleaning it properly after 3 games, refinishing it when needed. I would estimate that I've got about 150 games on it. It's finally lost it's hitting power. I can still get it to the pocket easily, but the carry is gone (lots of flat 7's). I think that this ball should be drilled with more of a leverage drilling, so that when the cover weakens, the strong drilling will still be there. All in all, a great ball from Track, 8 out of 10.
