SoÃƒâ€šÃ‚Â I need some education on bottom edge of skis if someone could be kind enough to share their knowledge. How does the different edges and combinations affect the characteristics Ãƒâ€šÃ‚Â of the ski? The Fischer has rounded edges, the Monza has 45deg to a rounded tail, the SS has 45 deg throughout, and the GoodeÃƒâ€šÃ‚Â I didn't pull out of the bag to find out. Thanks in advance!!
