In reply to matta:
I have quarks and totally love them so maybe just a bit biased....
My suggestion fwiw would be to get a nice pair of technical axes ideally with t-rated picks and if you're trying to save some money get a walking axe second hand - there are heaps on eBay etc.
With the technical axes try them in a shop to get a feel for weight, grip etc and pick something that suits you, your hand size etc. I found leashes a total faff so would always now go for something that has a grip rest and can be used leashless. Quarks or similar are not great for plunging into the snow as the grip rests get in the way.
