I recently picked up a pair of Rossi Freeski2 140's and FKS 140's. I was assuming that they would have the same AFD widths, but the FKS has the wide AFD and the Freeski 140s have the skinny one. Upon looking into it a little further I noticed that the Rossi Freeski2 120's have the same wide AFD as the FKS. Little confused as to why? Both FKS 140s, 180s, Freeski2 120s are wide, but Freeski2 100s and 140s have the skinny ones.
