I just bought a new set of USI X2 skis for my 2001 mxz 700 that I am stretching out to a 136. I am putting a cobra 1.32 on the sled and am wondering if I should use the power steering plates or the shaper plate that were sent with the skis. I also got the 6 inch shaper bars to go on the skis. I do mostly trail riding but am getting into off trail riding more. Also does anyone know a good starting set up for those skis?
