Hey, I am just getting started on some short tours this year. I am going to be skiing on last year's K2 Shreditor 112 in a 189. Right now I am thinking about mounting them up with Binding Freedom inserts so that I can swap between Attack 13's for resort days and Dukes for tour days. Does this sound like a good idea? Does anyone have any experience installing the inserts? I was planning on doing it myself but I am a little sketched out since these skis are brand new. Also, if I do get dukes, my bsl is 318, this means I can fit in a small or large duke. Right now I am leaning toward small for less weight, does anyone have any opinions? Thanks!
