Hi Jeff,
A_P_K threw a 300 with the new Hercules I got for him, at his request, from Ebay last season. Like Scott said, more depends on what your house is doing oil-wise. I'm using the Blue/Green Centaur, Storm Razor Wire, Revolution Renegade (like Dizzy), Power Groove Pearl and Solid more than anything else. I think the youngest ball in that list is 5 years old. If anything, the new balls are too strong unless you have high ball speed or lower rev rate.
