In reply to Tom F Harding:
It may sound like an obvious question, but will you be carrying walking poles as well?
Much of the time poles are as much or more use than an axe, sometimes using one pole and one axe and swapping the axe to the uphill side when you change direction on a zig-zag. If so, I would suggest these axes you have will be fine, especially if you take the technical gizmos off for the period.
It does of course depend on what sort of route you are going to do, if a full on technical ice route, things are a bit different.
