Hey everyone, looking to upgrade my 2010 with the S36 kit, t-motion and ds ski kit. Looking for opinions on what your have upgraded your the XP too, with either one of these options or two or all three . And if I were to pick one to make sled more "flickable" between the s36 or t-motion for the best bang for your $$$$$$$$$$'s. Thanks for your input. cheers.
