If you looking at low din bindings you may want to look into:
-Salomon STH12, make sure to buy driver toe not oversize. Oversize is a much less burly binding and as far as I am aware the FFG12 is the same as the Oversize and Atomic don't manafacture a Driver toe FFG12.
-Marker Griffon, the Griffon features better toe and heel pieces than the squire; triple pivot elite toe and inter pivot heel compared to triple pivot compact and hollow linkage on the heel. If possible try and purchase the 10-11 model as I believe that was the last one to features some metal.
-Tyrolia Peak12, never spent any considerable time on them, apart from a few laps, but from what I've heard a lot of guys are very happy on them. Be sure to get a couple lengthy reviews on this. Wish I could tell you more about these guys but I can't
Hope this helps, Joey
