TheWeazI wouldn't ski on either of those, I've heard the geze toe sucked, and the last pair of skis i found with those i dropped and the plastic exploded, I'm assuming yours are of similar age so the plastic is probably pretty brittle by now. The forza toes were metal at least, but my friend blue his knee on a set so i'd steer clear.
Also as the person above said, no shop will mount either of those. If your gonna use them please find some px12 or 14 toes to mate with the fks heel, with the right afd the ramp delta should be fine. either way your gonna have to mount it yourself.
the geze toe I have are almost brand new (few paint chips at contact points, the spot for the ski poles on the heel is only slightly damaged, etc.) and was almost definitely kept in good condition, so I'm not really worried about the plastic exploding. I was just more concerned about the principles of how the toe works, like P14 vs P18.
I have mounted skis before and I plan to do it this time
I'm probably not going to go for the looks, they are on a pair of well worn K2 extremes nearing 25 years old at this point.
