I am running Avon (Cobra's) I think... They are wearing well and have great traction in wet conditions. 8000km on the rear it looks about halfway toasted. I launch my XC hard and spin the tire quite frequently.
just for reference, i talked to an avon tech who highly recommended running 42psi front and 44rear for the cross country, he had a mileage figure for each 2psi of air too
