That's the problem with bowling, manufacturers are rushing balls to the market to compete with each other, and the overall quality of the product declines because I can't believe ball companies legitimately have time to test them before releasing them when they come out every couple of months.
I've only been back into bowling for about 2 months, but I haven't seen a single Ebonite/Track/C300 ball being thrown around here. To that end, the only Brunswick ball I've seen is the Aura and the only Hammer ball I've seen is the Nail smoke/fire. Seems like everyone is throwing Motiv, Storm, Roto and DV8. It also seems like their releases are spaced out rather than multiple balls in a few weeks time. Seems like they actually put time and effort into developing products that work, rather than just throwing whatever they have together and saying "buy me, I hook"...
