Been looking at the U-Turn Particle to use on the rare occassions i see a heavy volume of oil. A friend told me about the Arsenal Aggressive from Track. Can any of you Trackies out there tell me the differences in these two balls, and if one could handle more oil than the other. I am a old time stroker that still has good ball speed. Current arsenal is Columbia (Fear, Rebound)which is all I need most of the time. I get caught once in a while needing something a little stronger!
