In reply to McDuck: For snow, I'd go for G12's. One of the differences is the front points - I'm sure you're aware, but the G12 has a horizontal front points wheras the G14 has vertical front points.
The main advantage of this is the vertical front points go into ice a little better, and thin cracks on mixed stuff. However, this means they tend to 'slice' through snow a little - think of pushing down a butter knife through the snow pack. They're not that bad, but that's the best way I could think of the explain the principle.
Conversely, the horizontal front points of the G12 don't go into ice as well (this is all relative) as the G14, and won't necessarily fit in a narrow mixed crack. However, they are a bit more resistant to the slicing mentioned above - think back of a spoon on the snowpack (again, slight exaggeration but an accessible analogy.
As with binging, its down to personal preference - I prefer the crampomatic binging (G14 and Sportiva Baturas) as I find this the push the front points further out from the boot. Depends on our boot/crampon combo and preference (security, feel etc.) though.
Hope this is of some help!
