I had the x3 on my 14 pro, after riding the axys with the 2.6, I was sold. I do notice more wear on the edges but that is it. And as far as I am concerned, as good as that track works, I don't mind it being a consumable. As long as I can get 2 seasons out of it - and after one season, I don't think that is going to be an issue.
I hear you and also realize once these tracks are fully clipped they will be fixed and I might get several years out of it. Just another cost that I will need to allow for when buying a new sled. Lucky the Polaris is a couple thousand less expensive than the Doo to allow for needed upgrades. e.g. a-arms or braces, tether, track clips and some storage for a tool kit at bare minimum.
