I skied on a Spademan demo ski and had the classic straight ahead pre-release in a black diamond mogul field. I slid straight forward down the top sheet of the skis and when I hit the tips I was shot into the air like off a kicker on a jump. I went down hard on landing.
In the early eighties (might have been mid eighties) a friend built the first pair of release-able bindings for telemark skiing using a Spademan binding, What he did was mount the binding backwards on the telemark skis and then took the brass butterfly toe plate and mounted it backwards on the very front of the toe of the telemark boot. I thought that this was the highest, best use of a Spademan binding and tried to convince my friend to contact Dr, Spademan and help revive the company, but my friend wasn't interested so it never happened.
