In reply to Exile:
Ok. So differing opinions so far on weights. I was thinking without, but I've packed the weights and an alan key in my belay jacket.
I really like the axes for mixed, but have niggling doubts after the little ice I've climbed with them. We'll see!
In relation to pick angle - the mixed picks are steeper than the ice picks, but I don't know if it actually makes a real world difference(?)
