Very normal coordinates for a high tracker.
It doesn't make sense, but I track a little lower with asymmetric equipment. No matter what the asymmetric does down lane, the initial oil line which determines your PAP, shouldn't change. Don't worry about any small change your PAP might make with different balls. Your PAP should be measured with plastic or something that flares very little anyway. Even if it did change a little, the pin to PAP being off 1/2-1" means very little to anyone not PBA caliber, and probably nothing at all if thrown on a THS.
