Replying to Ski Tech question

So i just got some 191 BG's and those are going to be my 75% of the time ski. my other skis are Original ARG's and Original Chronic blends. the ARG's have the white/gray STH 16's and the blends have px12 jibs. The ARG's were mounted once, ripped out im guessing and remounted with heli coils, and then remounted to fit my boot with heli coils again.

I am thinking about putting the STH 16's on the new Billy Goats, and buying a 12 DIN demo binding for the ARG's. My thinking is that the ARG's will only get ridden on super deep, super stormy days where half the mtn is on wind hold so im not gonna be shredding hard on them...more sould skiing. And with the demo bindings, i can let friends and family shred the fat sticks instead of them renting some.

I am kinda worried about how the ARG's will hold up with all those holes in them. Also, how reliable are the demo bindings? How easy are they to adjust to different BSL's?
