In reply to TheseKnivesMan:
We did this as our first roped winter climb. We took 2 technical axes each but only ever used one - the other remaining attached to our packs throughout. Some photos here:

If there's any icy bits on the route you may feel a bit more secure with a technical axe but as others have said all the hard stuff is pretty easy to avoid by going up the snow slope on the right.
We stuck to the crest and pitched several sections - probably more than we needed to in retrospect but it was easier just to keep the rope out than take it on/off etc. If you intend to go up the crest then it's worth taking a rope as there's a few wee awkward steps - they aren't necessarily hard on an individual move basis but you'd not want to fall off.
Also, best to save it for a good day so you can appreciate the whole setting etc.
