Are there any skids from other snowmo companys that mount to a MM700 without any mods being done to the MM? I'm trying to figure out if I should get a long track kit from Hartman or if there is a chance some other skid would work as well while dropping weight. I've heard of M7 skids (153) being mounted to MM's but...Also comtemplating *gasp* getting rid of the MM for a diff., newer sled. Thoughts, help, comments?
