Here's mine:
Black Widow- best ball I've ever thrown, hands down. Very predictable, big backend, awesome carry and power. It's got a great arc all the way down the lane, and a BIG backend snap. You can swing it, or play straighter with no problems.
Total NV- great ball, more overall lane hook, big backend also, not quite as sharp, but doesn't "set", it just keeps hooking. Very versitile ball cover-wise too. The TNV can be very conditional at time though.
No Mercy- not a big fan of the one I had, although it was a good ball, just not quite what the Black Widow, Toxic, Total NV are. I wouldn't mind trying another with a different drilling sometime though. I didn't find this ball being a big "hooker", as compared to those stated above. Very conditional ball.
