Fritschi Diamir Freeride bindings have set the standard of what a touring binding should be able to do. With a din range of 4-12 it gives an option for a reliable released no matter who is skiing on it. The antifriction plates allows the used to be skiing in AT or regular alpine boots depending on the days activities it features an adjustable toe height to help facilitate this. The climbing posts give you 4 positions which allow all sorts of up hill climbing to be done with ease.
Only being pickey but it would be nice if the bindings had a slightly higher DIN for thoese situations when your bindings can't fail you.
The Naxo bindings are a good alternate to Fritschi.
