I'm gonna go ahead and jump all over this train. Glide, edging and endurance would be the best way to describe the difference in the FBV. Biggest thing for me was the way you cut the ice on the corners, instead of a solid crunch you could hear crystals falling on the ice. I think I need to tinker with it a little more, I was sticking more in my transitions then usual. Could be because I got new Step steel with 100/75 and the height of the blade is making the difference. Any ideas guys?
