Its kind of interesting to me that 7 tooth drivers are the number now. TS went with the 6 tooth as well and tucked everything up in the chassis in 15. This made it tough to add a 2.5 track which was short sighted on their part. Artic Cat has dropped and rolled their sleds like we all did back in the day, CMX has a shallow approach angle much like the kitty cat sleds. All the kits can now take a 2.5 or better.
All this is starting to sound a lot like a 13 14 TS kit. Add the new DTS track, Raptor triple rate springs, ski of choice, some shocks and voila. If only there was a belt drive......

6 tooth does not roll easily, the 7 on CMX rolls across the concrete, 6 will just skid, That equates to free track speed
