Replying to Lightweight Binding Suggestions

I just bought a pair of 185 2010 JJs. One thing I've always loved about this ski is how light it is. So keeping with that tradition, I wanted to buy a lightweight binding that will hold up well too.

I'm like 5'11, 155lbs.

I'm currently considering:
Salomon z12 Ti (Lightest)
Marker Griffon (Mid-Light)
Salomon STH14 (Least Light)

I have never owned a pair of bindings other than Looks until this point, so I have no experience with any of these. Can anyone vouch for their performance/durability/weight or lack thereof?

Thanks.
