I went from an 19 Alpha to 22 na Matryx. Kept the Matryx cause I really liked it but got the 600 Catalyst last season as I’ve always been a diehard Cat guy. Wasn’t the greatest snow year but the Matryx didn’t see a snowflake last season. Spent everyday on the Catalyst. Matryx will be going bye bye this year….can’t wait for the 858 to show upHoping to get some real comparisons between the 9R and 858 Catalyst. Being a Cat guy for decades, my loyalty is with Cat buy after one season on the 9R, I am not afraid to admit it was the best mountain sled I've ever owned. I think they'll be easy to jump from one to the other. There was barely a learning curve coming off my Alpha to the 9R.
