I'm 6'3 320 lbs new to sled wrenching had a 440 when I was younger never had any problems. now I bought a 2004 polaris pro x2 800 kept smokin belts to the point of cracking the primary 700 dollars later I am still slipping the belt. does good at most speeds but when I hit even a little powder and need it my belt slips where should I start heavier springs,wieghts? I'm assuming there are are other 300 pound guys that ride
