mrepps-24,
I have to be honest, you're leaving out a lot of important details that would help us give you a suggestion, but I'll try to give you a few options nonetheless. Since you are currently throwing Hammer, I figured I'd present you with some good choices in their line:
Hammer
Blade Pearl--medium/medium heavy oil with clean backends
Blade--Good for heavier mediums with clean backends
Turbo Diesel--Medium/medium heavy and some carrydown
Diesel Reactive Pearl
Diesel Particle Pearl

Bowling is without a doubt the dumbest, most pointless, most idiotic excuse for a game that has ever been invented. So, what time are we bowling tomorrow?
