I ran one camo extreme 163x2.5 2.86 pitch on my Carls 860 big-bore Dragon, it was used when I got it and showed a little wear but no damage, ran it a couple thousand mountain miles more before finally selling the sled. Even though I did catch a few trees / rocks over the years, never damaged it, not 1 torn or missing lug when I finally sold the sled. Also ran the same model track but in 155 on my wifes sled (700 dragon), sold that sled and upgraded and kept the track, which we ran on her 600 Pro, and later on my 800 Pro... same story. Tough track. I only personally know of one person who had a major issue with it where all the center lugs came off his track, I would say much better track than the stock 2.6 Polaris track in almost all conditions, but a bit heavier. Small price to pay for not having to put a new track on every couple years. And not having the lack of braking the stock 2.4 had on hardpack where the lugs just roll over and you keep sliding downhill... did that once, heart attack time... Better on trails that the stock 2.4 also (know by experience) and probably the 2.6 (stiffer lug). Hope this helps.
