I have a 2018 129 Factory edition attached to a 2016 husky 501fe. I ride the steep and deep mountains out here in British Columbia. I went back and forth a million times when I went to purchase a new kit, but I can say that I am extremely happy with my choice. I have had zero breakages or rattles or any of the stuff I read about on the 17 kits. The customer service has been hit and miss, but I have been in touch with them recently and they were great. They also told me they are getting ready to launch a new website and are going to be working hard to rebuild the brand. I just ordered the new slider dampener that they released for my kit that is supposed to reduce trenching, but honestly I never really noticed a trenching issue. At least no worse then the timbersled, camsos, and yetis that I ride with. I am extremely happy with the performance of my kit. It is noticeably easier to weave around in the trees then the timbersleds I ride with especially, and there is never any place that the other kits go that I can't. I don't think any 1 kit on the market is "Amazingly better". I have ridden with them all and the rider/bike/setup have a lot more to do with it then the kit in my mind. This is just my personal opinion, but if you can get a good deal on one, I wouldn't hesitate to buy it. I would recommend the mototrax to anyone.
