I've had a 19 165 and 20 154 alpha. Funnest sled ever but 19 had quite a few little things go wrong. 20 has been flawless. I'm riding it one more year and then that's probably it for cat and i. I will probably put an alpha skid under a polaris. They are just better equipped. More power, better boards, better accessories, better fit and finish, easier to work on. You get electric start without having to settle for a trail seat and smaller, heavier tank. I put burandts tank on my wife's kaos and that thing is awesome. Oil off the clutch, lighter, narrower and seat height is perfect now. I also run grizzly gauntlets and they were made for the polaris. I have to bolt brackets on the cat, that suck, and i broke the grip in half from rolling it. I love the alpha rail and track and the fact there is less feedback, through the bars, when on edge but everything else is so far off compared to the others. They would really have to change to keep me for 22.
