If you have a shorter straight, the 15 or even 14 might be fine. Problem is you can only go so low before the punch will overwork the stock slipper even with FT pads. I run the thin slipper pad up front in case it helps balance it out so it's not all rear slip.
+1 on this. I've been running 14/62, I've also been glazing the slipper pads pretty bad. I switched to 15t and it's a little better. I've come to think that the smaller pinions on the 4-pole motors is too much for the stock slipper.
I'm going w/ the clutch basket...
