Just to be remotely useful:
The Freeride is a great no-maintenance binding good for people who are not doing super-long tours, are fairly heavy or ski fairly aggressively, and are coming straight from lift skiing.
There is a lot of slosh in the binding compared to a real alpine binding. There is a lot of plastic where a high-end alpine binding would have metal. Your feet are higher off the topsheet than an alpine binding.
It has been redesigned for 06/07 (well it actually has finally been imported from Europe, where it was around last year).
The older designs had a nice habit of occasionally disengaging the heel on some jumps when the ski flexed the heel out. This is supposedly fixed.
The Dynafit binding is more torsionally rigid than the Freeride, and the boot is lower on the ski much like an alpine binding. They call the release a din 10, but in reality this will vary a bit based on the flex of the ski. You can lock out the toe and the release is "higher". Probably best not to be jumping in them.
There is a learning curve to the Dynafit system, and your boot choices are limited to those with the pin holes. The weight savings will literally make you feel like you are running up the hill.
The Naxo bindings from BC Access now go to 13 if testosterone is driving your purchasing decisions.
I've used the Freeride for about 3 years along with the dynafidgits and they are both great products with their own drawbacks. In the end I have found I like having both. I wouldn't want to work a season pass on Dynafits, but some people do, esp if they are just seeking out the blower days when it's too dangerous to go outside the area.
