Beginner mounting question
My friend has skied a very little bit but wants to get into this winter so he will be coming with us and pretty much be thrown into the fire. We were talking about mounting his skis and I was thinking center b/c he will be skiing a good amount of park once he gets going. Do you think it will affect a beginner that much. I was kind a thinking it he won’t know any better and it won’t really mess him up while learning.
