I put a CAMSO CE 2.5 Extreme on my 11 PRO 163 with SLP stage 3, from tracks USA 2and half years ago and for 2 seasons was excellent IMO as good as the 2.6 series 6 as I rode with 2 AXYS buddys. That sled just went away yesterday to Montana ( a friend bought it) so I now will have to get used to a new AXYS 800 163 with the series 6 track, i"ll do my best to get used to it as quickly as possible!
