I mounted a Z12 Ti on a 177cm Volkl Matra the other day and the whole thing weighed in at 11.5 pound for a pair. It is incredible how lightweight the binding is. I skied them this spring and have 2 pairs on skis right now for next winter. I was very imnpressed how much nicer the torsioanl rigidity of the binding is over a Rossignol/Look. I never thought I would be saying that about any binding manufacturere, but I think Salomon has made the best binding for 2007. Dont get me wrong, I love the Look/Rossi bindings, but the new Z12 Ti's are incredibly light and rigid.
