A friend uses some fritschi bindings, cant remember the model, probably the freerides. They are pretty light, although weight becomes very important when you are the ones sliding them uphill. I would love to get a pair to put on some old fat twins for touring around the place, might get around to it someday.
Im surprised no tele guys have got on here yet telling you to try that. Its damn hard to learn, but when you get it, and you look good, its awesome. If you get the patterned base skis, you dont even need to skin up, although they do slow you down going down the slopes. Remember, 'free the heel, free the mind.' Damn hippies.
In tractor pulls, a 'full pull' is the best you can get. Ahh, how sport mirrors life.
