Out of a group of eight people lapping a damp ring together (at the same pace and on the same line) only 2 weren't complaining of have little slides in the greasy conditions. Both wee on big v twins (one Buell one 996), both were on Pilot Power 2CTs. I've not tried the Pures yet but I'd buy another set of the Power 2CTs tomorrow if I needed them, but they last so well i don't.
