STH 14 drivers are in a whole different league than griffons, but they are twice as much also. I have griffons on my jib skis, jesters on my park skis, and STH on my skis where I could die if the binding fucks up. They both work well, but the STH is simply a better binding in every respect:
1. the STH 5 hole pattern on the heel is more robust
2. the STH heelpiece has legit lateral exit
3. the STH screw mounting width is substantially wider
4. the STH toepiece is so much better it's absurd. Adjustable toe height, adjustable wings, metal construction. Not to mention the weakest part of the griffon is the toepieces tendency to develop some play after a few seasons.
5. for all of those advantages the STH 14s are about a tenth of a pound heavier and the STH 16s are a quarter pound heavier. That is like wearing a heavy pair of socks, it makes no difference.
And the price shows, my griffons and jesters have cost $125-175 and my STHs cost $190-300.
The griffons are really nice bindings. But they don't even come close to STH quality or reliability.
