In reply to satori: Sorry didn't see this last night.
I use the Ally ones. Lighter but less durable. Hard to get hold of outside of the US/Canada, I think I got mine from fastandlight
Never used them in the end on any real snow as it just didn't happen last winter in Snowdonia.
Walked with them a bit on day in Snowdonia in Snow, felt OK, in a pair of solamons. They wrao around your shoe more, one band around your ankle IIRC.
havn't used them in anger so can't really testify to their suitability in proper conditions, but i've spoken to a few other runners who have climbed grade 1's in them and think they are fine.
If I use them in anger this year I'll write a review of them.
We also use a lightweight Camp ski mountaineering axe, XLA 210, I used that a few times.

It's fine, very light so would bounce of ice I reckon, but seemed fine on hard snow.
