I purchased this ball last week and wasn't sure on what it would do. At first, the ball skidded too much, so I used a green scotch bright pad to dull the surface. What a move! I'm a down and in player and really I do not like to cover a lot of boards. For me, this ball holds the line length wise and turns to the pocket, without over-reaction. It doesn't over flip (ie... burnout) and the only issue may be carry down, if you don't put a lot of hand in it.
Last Sunday, I shot 1240 in five games, not bad. This was practice, but the lanes were freshly oiled, to a league shot. Last night, shot 299 first game, in my scratch league.
The ball, clears the heads nicely, with a strong backend. It's not a flip, but a strong arc/flip. The ball doesn't die and the pins get knocked low and hard. Usually, there are no pins on the deck, they get explode when the ball hits.
Great job Hammer, let's see how the longevity will be with this ball.
