In reply to thomaspassmore:
I recently bought some ice screws for my first experiance of climbing on ice. I thought of buying the same ones but having spoken to a few mates with experiance they advised against them.
On recomendation I got some DMM revs (£33 from rock and run. It was a good decision they start very very easily, are not hard to screw, and rack well. I tried other makes belonging to my mates last week in la Grave and think the DMM revs are best. Lazer sonics go in faster thanks to the handle but are harder to start and a bugger to rack. The general concensous between us was of the five of six brands we had the DMM's were best.
Hope that helps
