I still have the turbo cat for now. I believe the pro chasis is hands down the most capable one out there for me and what I do on a sled. From my experiences on the ones that I spent time on last season, they are flat out awesome and work just a bit better than the M, and requier just a bit less effort than the M. And personally, that is something to be very excited about.
I have nothing against the etec, but I HATE that akward chasis it currently sits in.
LOL I guess there is a bit of truth to that. BUT, you have to remember that Erik is a freaking animal that is used to riding 280+ horsepower and sub 440 lb sleds. And not to climb hills, but rather make the most obsurd nasty technical lines through the trees, across and up hills, and through creek bottoms. He is one of the very very few people that can truly ride a sled with its skis always pointed up. That being said, he replaced the stock pro skid with a lightweight cat skid until his timbersled was installed. The timbersled skid brought control to his sled. By the end of the year he had it setup retarded! Low air in his rear shock to get back that skis up action. I rode it for a while and it was akward and difficult for me to handle.
