What does the 2.6 not do that you feel a different track might?
I really liked the 2.6 155. I thought it was one of the best tracks in a stock set up. I didn’t feel I needed to gear down or overly clutch the sled and %95 it went where longer track sleds were going and I was having more fun than on my previously longer track sleds like a 163x3 or 2.5 and so on.
I wasn’t blown away by the CE 2.5’s. Had one on a Doo for a few years. Different sled but tried a Axys with one and wouldn’t say it made a noticeable difference in the short time I tried it. You could look for a 3” powder claw but going to be changing drivers as well.
