Captain,
With Lane#1 balls having an apparent sensitive to pin placements, could it be that your PAP measurement is off and your CB's pin placement is not accurate enough?
With your revs and the CB's low RG and very high flare potential, I think you need to place the pin over the bridge and have it be in the 4-4.5" range (pin to PAP), with around a 90-100 degree core angle. Otherwise, it may burn itself up in the heads and midlane. As someone mentioned, the CB's highly polished cover may be susceptible to carrydown; I am not sure about that myself. However, the PK 18 cover variant, that the CB has, should, with your revs, be able to handle mild to medium carrydown.
