heres my situation. i work at a shop, and can get FKS's for dirt cheap. Now, i am also building skis this season, and we will be utilizing threaded inserts to mount bindings on our personal skis, to allow the use of one or two bindings with multiple skis in our quiver.
so anyway, the FKS do not have wide brakes. so you bend them. however, wide brakes on a midfat ski= no good. i also dont want a high din binding for my park skis, 12 is plenty. however, i want the extra umph of a 14 din. so, heres what im thinking about doing. i have a set of OLDschool turntable heelpieces, which are identical to newer ones, just the housing is differnt, and the halfcircle retainer plate is plastic VS aluminum (any issues with that guys that have done this?). the only problem is the dins are maxed at 10. what about scrapping a pair of beat p14s, and installing the higher din spring in there, and using it with the Pivot 14 toe? this would be a shitoad cheaper than buying two pairs of FKSs, and i can get the FKS12s for next to nothing. pretty much, my question is are the springs the same dimensions from line to line?
