I currently ride a F800 with a 129 track. I ride mainly trails but really enjoy unplowed logging roads and some off trail riding. I am looking into upgrading sleds this off season and would like to get a 137 track. So, I am looking for a crossover sled with good trail capabilities and be sufficient off trail. My idea is purchase a 137 with a standard 1.25 track and purchase a deeper lug track to use on my one trip that we go mainly off trail. One sled, two tracks. Good idea/bad idea? Looking for insightful input on this.
