My last 5 tracks have been 162 2.25, 153 2.25, 153 2.6, 162 2.6 and now the 162 3.
except the 3" 156, I've got the 162 3" now and after all these years of riding I can honestly say that I enjoy the 162" length the most.
I think the 162 3" does a great job of getting the sled up out of the snow, as well as holding an edge and is the best of all of them on downhill braking. I also think the longer track helps with the super steep side hill, and also allows me to ride a bit slower in the tight and technical trees that I enjoy. Also makes it when I have to get on it for a quick climb in the trees much easier as it doesn't trench as much for me. the 162" also does a better job for me at 225 lbs. Those are my thoughts after 20+ years riding basically every make of sled out there, Pro, XM, m series, dragon, XP and PC. I know dudes are always saying that shorter is for the more technical, but I think with the chassis advancements we've seen in the past few years, most track is an advantage and isn't any more difficult to ride. Can't go wrong either way though that's for sure. Those are the best 2 tracks out there IMO.
