I have about 40 games on my Doom and it works just fine. In fact this is the best reactivce pearl ball I have ever owned. I will post again when I get about 60 games on it to say if the cover is holding up. I'm willing to bet it will be just fine.
I'm starting to notice that some bowlers are using this ball on conditions that it's not meant for. If this ball is sliding too much then why are you using it? That should be a direct indication that there is probably too much oil on the lanes for this ball.
I really feel there are a lot of bowleres using balls on the wrong conditions.
