skis suck for tramps, you can rip a hole in em easy. even if the edges are duck tapped, I came down on my tramp with the tip of my ski first and ripped a huge hole in the material. you best bet, is to either make the skis out of cardboard, or buy a sheet of plexy glass, or what ever the stuff is that they put on boxs. and cut them into a good lengthed ski. then sand down the edges and tap on some old shoes. voila. there ya go.
