Thanks very much everyone. It sounds like it won't make much difference for a newbie. Noted that bashing rock is to be avoided.
beardy mike and nniff - thanks for the point about the technicality of the axes. I've thought quite a lot about this, although it's all been a bit theoretical as I've not been able to head out and test different axes on the terrain I'll be starting on.
I had considered that something like the Apex might be a bit extreme for starters. (Quarks and Bandits seem a bit less aggressive.)
My main thought was to try and pick something that could both get me going and see me through anything foreseeable. From what I've read, these axes are still okay on more moderate ground (even the Apex), and that from about III onwards they start to come into their own.
Whereas if I went with something a bit less aggressive (e.g. Flys, maybe Sum-Tec) then I'd potentially be looking at another purchase in the not so distant future. I had looked at the North Machine, but the lack of a spike put me off. (I know that plunging with curvy axes isn't great.)
Sounds like you guys might have a different view about the suitability of these axes for starting out though.
beardy mike - when you talk about shallow angle ice, what sort of angles do you mean by shallow? (Roughly)
