I never got along with the seating position was the biggest issue. I had no other issues I can really think of, the suspension and ride for the most part on my old RR was pretty great. I was looking to get more power than my 6000 CTEC, and I hate the seating and ergos on the Ski-Doo even more than the Cat, so I started looking at Polaris. Everytime I sit on an Axys it feels like that is how I am supposed to sit on a sled. It was only about an hour demo on a mix of mostly Indys, my favorite being the XCR, but I knew pretty quick that was all I needed to know I was switching. The seed was planted when I rented a SKS 155 out in Yellowstone last year. My only fear is that I wont like my 650 VR1 as much as I loved the 850 Indy XCR I demo'd, but I guess I will find out!So what are the major differences you noticed? I ride a procross now but have a 650 ordered. I did not get to ride one.
