hey what are the disadvantages of having my bindings mounted towards the back of my skis? i have 2003 volkl vertigo g4's w/ marker titaniums (i dont ski park that much, so rails aren't a big deal to me). i mainly ski bc, but can hold my own on big kickers. Im 5'10' 180 pounds, din is at 9.5. heaven to me is untracked, is it bad if my bindings are mounted farther back?
