In reply to Alexander_Metcalfe:
As others have said its a lot of personal preference, but as it seems you're looking for some general inspiration - here's what I use:
Fischer transalp 80 skis in 163 cm, with fancy plstic skins and dynafit tlt superlight bindings.
Why?
They're incredibly short which makes them great on the pack for climbing. Also makes steep accents a breeze cause they're more like snow shoes and are extremely controllable uphill.
At 1125g per ski they're basically not there.
80 mm underfoot has been sufficient for all but the worst of power days. However, whilst I'm no powder hunter they could be wider.
The profoil skins are absolutely brilliant.
On the negative they are pretty choppy on hardpack and very slow in late spring/ wet snow.
I'm not that fussed by the actual skiing part and am way more interested in the climbing. Thus they are are essentially what I consider an approach ski. They were also incredibly cheap.
But as davehk says, let us know what kind of ski mountaineering you're planning to do with them
