My buddy moved to Florida, he left me 2 bricks of SWIX UR8 (red, 14F-36F) wax. As far as I know, they are basically just basic SWIX universal wax. Is my understanding correct? I don't race but I do like going fast, east coast, mostly on man-made groom snow. I can't find much information on it. Are they good enough for what I ski? It's free, so I can't really complain.
