Yeti TS and Camso
We just had a day out swapping bikes with a variety of kits: Short version from my point of view. I have owned Explorer, 2Moto, many TS, UFO and now Yeti so have some experience.
Kits for the day: Yeti 129" (no RRS strut yet), couple TS short track, a 137" TS, 137" 2016 SX with TSS and 137" Camso.
On pure ice road Yeti best by far of any ski I have used including the TS with center triple carbide.
In 8 to 10" of wet snow on road: Yeti "really" bad, TS OK and the Camso good.
On bumped out road: Yeti best, next TS SX, TS short track, last Camso.
Results of doing climbs in 28 degree weather 12" of fresh almost powder, dogging stumps and downed trees: Compensating for 30 years age difference in riders the Yeti seemed to hook up better, next the TS SX 137" and the Camso 137" were too close to call. Short tracks had a tough day.
My Yeti on a 2016 YZ450FX sits higher than any other kit I have owned and I have put a lot of work into lowering it just to get toes to the ground. Maybe the RRS strut will help that if it ever gets here. Big decision of how much to pay based on what fine points you are looking for. Good strong riders seem to be able to ride just about anything and that leaves me out. I need every advantage I can get!
