In reply to ffati:
Ah mate, enjoy! MY pal and I climbed it late September 2015. It's virtually a sport route with pitons all the way up. Some better than others!! Some are very dodgy.
We placed maybe half dozen bits of gear each on the whole route. Rack of .5, .75, 1, 2 and 3 camelots, about 10 medium sized wires, 10 extendable draws and 5 normal sport draws though I think you'll be good with 10 or 12..? I'd still take 15
The rock fax guide proved super useful, especially for the descent. The best route and descent description I've seen.
We finished in the dark and had a cold uncomfortable night at the finishing ledge. Had we have known, we would have traversed the ledge around to the south face where there are much better options.
It's a proper north face and was pretty nippy but this was late September.
Thick mountaineering socks
Soft shell trousers
Thin base layer
Thicker Ice Breaker
Softshell hoody jacket
Medium weight / warmth gloves at the belays definitely a good idea and stuffed them inside jacket whilst climbing
Beany
3L Bladder, bars and chocolate etc
Bothy bag; if you're like us, slow and prone to ledge bivis, a bothy bag is a brilliant idea.
Use the lightest approach shoe you have. It's a super easy walk in
Hope the weather holds out for you and start super early to get the jump on crowds. I understand it gets crowded in season. We had it to ourselves out of season
