In reply to DrUmbongo:
As was already mentioned quite a few times already...
For easier climbing, you'll be fine with that Evo you already have. And if you think you'll only going to be climbing something slightly harder, that will also require another axe... well, get almost the shortest one with a hammer (like sub 50cm).
But if you actually want to climb, well I'd get a matching set of proper tools and dedicate the Evo you have for walkin' and easier mountaineering. The good thing is, that pretty much all technical tools sold these days are good... some just are better than others (for certain types of climbing, or being more robust and so on).
If I were to get my 1st pair of technical ice tools now... I'd prolly get the new DB Vipers (or more likely the old orange version at a good discount). DMM might also be an option, and perhaps even Grivel Machine 3.0... All of those non-ergo tools will be perfect for about all climbing (perhaps not extreme drytooling, though), and can even used on easy snow (accessing, descenting or topping out the actual climb). But since you already have a snow-plodding axe... perhaps you might push it a bit and get those ergo-tools (Nomic, Fusion, Fuel, Tech Machine, Switch...).
I only have Fusions these days, and use hiking poles on easier glaciers and snowslopes, granted I might take a BD whippet (self arrest hiking pole) with me to replace one of them normal poles... if the glacier looks rowdy or the snow steep on the descent. That said, I've been messing around on steep snow quite a bit (with skis on the rucksack or on my shoulder) sans crampons and with normal skiing poles... So my perception on what is "safe to do" might differ from those with pure mountaineering background.
