So im buying some new skis for this year that i'll probably use next year and i wont be able to afford fks bindings at the moment. Anyway if i mount axials on them now will i be able to use the same holes for fks's in the future?
No, the axial and fks 140 toe are the same, but the heels have a different mounting pattern, not sure how those holes will conflict, but you have to have 1cm between the holes on a remount, so you may end up having to completely redrill the ski.
Unless you really need the FKS just use the Axial's for a couple seasons. They are nice bindings, not 14 din, but still probably will work fine. Then you could get FKS when you get new skis in a couple years.
honestly if you can find a little extra $$ to buy the fks do it, they will last you forever and you will save money in the long run. I've seen axials break like 2-3 times (the heelpiece rips out of the track) whereas FKS are nigh on indestructible
