Disturbed from Roto has been very good to me...if you can find one, good stuff.
For a benchmark, I tend to like stuff that is not highly polished or pearl as I want the ball to be able to read the lane and tell me which way to go, if I need to go away. Also, don't want anything too sanded or gritty (particle/etc) as that can also mask reaction.
Thus, a nice full solid cover (no hybrids) around 2000 abralon. Thus the Disturbed, but depending on what weight you throw, the Storm Wipe Out fits nicely in that slot, also the Hy Road solid (if you throw 14 - check out the specs if you throw 14#...you will see why) or the new Fight as that ball looks real good, but who knows for sure until some get delivered, drilled, and used.
