I'm probably gonna end up going with the Beat'n. I was at the pro shop tonight and I showed the pro shop operator the diagram of the lane condition that my coach drew. He said what I'm looking for is something that not necessarily a "skid/flip" motion, but more of a "hard arc" motion. Obviously I don't want something that starts to roll at my feet, but yet, I also don't want something that's gonna be too skid/flippy, b/c then I'll end up washing out a lot. I also told him that my coach thought the NMB was a good choice, and he agreed.
Don't get me wrong, I still think my Eraser is a great ball; it has good length with a nice, arcing backend. However I don't think it's strong enough to handle the new condition that we're bowling on.
The only ? that remains is whether I should buy it online, or whether I should buy it directly from the pro shop. Any suggestions?
