"I mounted mine at center, which is 7cm forward of recommended. They are centered on the sidecut at recommended, so where I had them mounted there was alot of tail on snow and almost no tip. I would only recommend this to park skiers and strong skiers, as it is really different. On groomers the tips would fold when flying down due to the softness of the rocker and lack of ski contact with the snow. Again, this is only a problem if you mount at center."
I'm looking to mount some S3's at center and was curious as to what this person means by "alot of tail on snow and almost no tip" and "the tips would fold when flying down..."
