In reply to Merlin:
If you are based in the UK, I'd suggest "Himmelsfinger" at the Poncione d'Alnasca (Ticino, Switzerland) - logistic & flights would be much easier / cheaper than for the US big walls - although it's a three day route at least.
We tried it last year early september as a first big wall (bailed after p5 due to bad weather). October can be quite cold up there and the shorter days won't help either...
Topo says to bring a portaledge, this can be avoided:
day 1: fix p1-3 (possibly p4 if you bring a 3rd rope), go back to the hut
day 2: jumar/climb to the ledges at the start of p8
day 3: top out & descent (or bivy at the summit)
With my very limited big wall experience, I can't really comment on the grades. I've heard that grades are somewhat softer than US new wave aid grades. Guidebook says VI / 5.10 A3.
The pitchess we did were quite safe, even the hook sections on p3 & 4 had just enough bolts to feel "kind of safe".
