A riding buddy of mine bought a new 2016 154 with the "T-3" package that was the 3 inch lug. That track was only used for a year, I think then they changed the pitch. It is stored inside during summer months, suspended, and the track rotated every month. Winter it sets on his sled deck. We ride just about every weekend. He noticed some odd cracks running perpendicular to the track not on the lugs like you would see from rips. He does not run it fast on hard pack. Anyway Ski-Doo has come back and said it's dry rot. On a 3 year old track, on a sled with 2800 miles. Anyone else run across this? thanks.. Mark
