In reply to neuromancer:
Difficult to really know what your ski level is. I would say if you imagine you will be falling over or falling over a lot, you're probably better off with at least a more robust pin binding with some give in the toe, e.g. Radical 2 and heavier. That will be more appropriate for your skis/boots and a set up of the type that many people would use as their only set up.
A more lightweight binding will of course work, but it's probably better to be a very good all conditions skier and/or to ski them more conservatively, so that you are falling over not at all or only very occasionally.
With a heavier binding you can push yourself with more confidence when skiing piste, sidecountry etc., which will help you become a better skier etc. They will have a slightly better feel when skiing.
Anecdotally, a lot of pin-binding injuries seem to be low speed, awkward falls where you don't generate enough force to release the binding.
Skiing crud is easier on a heavier, stiffer ski.
Don't buy a binding that has been released in the last 1-2 seasons. There are always problems and you're better with a more established model.
