I switched seat time between a '17 XCR 800(mine) and '19 Indy XC 850(dad's) last year.
I still feel the Rush has more fun factor on the trails with the uncoupled suspension. This is really being picky though! Both are phenomenal trail machines.
Indy does better in the stutters and little more plush. The rush does better in the big whoops. The 850 is a rocket!
I picked up a INDY 800 129" last year and loved the trail mannerism. I previously has numerous 136" Switchbacks from Polaris. I don't think you will notice much difference at all going from a 121 to 129" track. The only time I miss my Switchback is if I find really deep snow off trail.
X10 High Flyer!
I had the 18 800 Pro-S in December of 2018 and the 121 was way to short to hang with the guys with the 144's. The *** end was swaying all over the place with 6 inches of new powder in Houghton.
If you ride in WI, you should be ok. The U.P., get the 136 it's only $200ish more and you get it all back at resale time.

Yeah right....you didn't have it setup correctly, clearly. Spend some time and tune the suspension to your weight and balance. 136-144 are totally unnecessary unless you're off trail.
Just more weight, and handle like boats. I had one 136 inch track, and would never buy one again. The difference in handling in tight sweeping trails is just too much to give up, for the perception of better hook-up. And the fairy tale about resale is just that.
Hey Bear was that about the time you got cold feet with your Polaris? Joking aside I am considering doing a comparison of a 850 ski doo vs my 850 XC. Know of any deals to be had on one???
Rider size may matter too, I am 6'3 300lbs. Each of us are different.
I actually bought the Polaris tool to set-up the shocks for my weight.
There are two guys out there (you know who you are) who helped get me unstuck (the worst in my life) north of Houghton last year with their Assault's.
I liked riding the 800 Pro-S near home in Green Bay, that sucker see-sawed like a mug (as advertised), dug in on acceleration and the ski's bit corners on deceleration.
Add real snow though and any 121 is gonna wanna stay home.
I had several 120-121's Rev's since 2003 and loved them (cheap, fun and great resale) but as I started riding north of Watersmeet the Gade had to be considered. Once I found out it was $180 more I bought in.

What is this set up tool you are talking about and where can you buy from. I have a 2018 Switchback 800 and would like to purchase a tool.
