I did a review on this all on 6/10/2003. It's a very good Columbia piece that I love taking to tournaments. Extremely strong core. Goes long, but revs hard. Once it starts turning, it doesn't usually stop. I like it because the cover allows me to get thru the heads cleanly. I've got a 16#er drilled 4x4 stacked leverage, and I've got a 15#er drilled Rev/Lev, that I can use on a variety of tough shots. This ball is sneaky strong. Don't sleep on it.
Ps. I use to have both balls drilled label leverage, but the cores were just too strong, and my speed too slow to be able to use them for three games. I'd move inside, but the balls would just keep on coming on the backend, as lanes transitioned. I know this sounds weird cause both balls now are drilled STRONGER than I had them originally, but because they are so strong, I can throw them slowly....and they burn-up a bit before getting to the pocket, making them perfect for my game.
