Guessing Carbon Paste is my next step.
Re: the seatpost bolt — No. havent greased it. Not sure that would help as i seem to be reaching the maximum tightness possible and then it just stops. Never had a problem with my old Easton Seatpost. (for sale in the classifieds btw)
Get some carbon paste (incidentally I think the Park stuff is "carbon and alloy assembly paste" or something similar) in there and I bet it'll stop slipping.
