I replaced my LX bindings that were purchased during the 2005 season and these were a definite upgrade from those. Though they're geared more for all terrain, I found they had pretty good flex and as I no longer ride park, they did well for my down hill riding.
My major complaint is that after 2 days of use in CO powder conditions, several screws were coming loose. The base plate screws didn't come with washers which probably explains why those were coming loose, however I can't explain the screws coming loose that hold the plastic straps or the highback.
All in all I was able to tighten them and had good runs. Perhaps I was shredding too hard ;-)
