I love the Salomon s912TI 1080 and they are so lite but thire orginal idea came from the Look company but you pay a little more for them.. Id go with the Salomon but if you don't mind money go with Look. All the W/C freestyler's are on look...
I have the 912 ti's on my pocket rockets and absolutely love'em. I tend to see a lot more looks and rossi's when I'm in the park though. I'm loyal to Salomon and would not change. The only problem I've had with'em is I broke a brake this last year in Vail trying to land switch...I still think they're the best even though I'm stupid.
Yeah they're fine for smaller waisted skis too. It just depends on the size of brake you have on it. I can't remember the exact sizes but if you buy them from a salomon dealer they'll ask you what size brake you need, just tell'em the smaller.
I have both, and there both awesome bindings. I don't know how much the 912 tis are but the jib bindings are expensive so I would just go with the better deal.
