Today riding my sled burned thru the hifax. It was only 50miles and I thought I was getting into enough soft snow (bear in mind I was riding in Minot, ND and my sled is a 07 Summit 144). The question is should I fork up the money and get Hyperfax or just buy another set of stock hifax and remeber to put the scratchers down. Sled only has 500miles on it.
