I just bought my third pair, and will buying my fourth pair of Look/Rossi Axial bindings in two years. (yea I buy a lot of ski gear) In my opinion, they are the smoothest binding on the market. Rarely do I have problems with prereleases, and when they do let go, its smooth, not jerky on the knees. I can also ski 1-2 full DIN settings lower on these bindings than on Markers (pending the ski). I have also found that the "turntable" type set up allows you to more easily put you ski back on in deep snow than other bindings.
Just my thoughts.
