Since cat came out with a new primary and secondary does that mean they are admitting there is a problem with some of these belt blowers out there? Sounds like it to me, my sled seems descent at 1000 miles per belt but still I think wee should get the upgrade. What do you guys think. What about going down to the 1 1/4 track and extra idlers you think the realize slide wear is an issue too? I love my 2013 looks way better than 2014's but man some of the upgrades I want like the slide action for the xf skid.
