I've had this for about a half-season altogether, and must say it may be the most versatile ball I've ever had.
At first, I left it at 4000/polished, and for my THS, it squirted a little too much. Took the polish off, and it's incredible. I stay with this ball all night long. I can play it straight up 10 or inside from 15-5 or 20-8 and it still comes back.
I don't think you could find a better ball, great price notwithstanding, for a THS league bowler.
