No you are right, I made a mistake.
Hey guys, I finally got my 78's retuned, and they ski great. So that's the key: regrind base, reset edge bevels. I just went with 1/2 to match my other skis for comparison. I may try a 1/3 later. Held on all the hard icy snow a hard spring day at squaw could throw at them. very fast and stable, which was good, since I was chasing Jonny Mosely around a mountain tour. he couldn't lose me on gold coast, dammit! what a great guy, and my god, what a skier!
