In reply to Cuillin Calling:
You don't need trad gear. You will probably climb the whole route without belaying at all, except perhaps on the Moseley slab. You should also be down-climbing most of it. Route finding on the way down is hard. It is very easy to get off route on to the exposed east face. You need to keep much further left (facing down) than you might think.
It's an iconic peak but a terrible, overcrowded route. Most of it is a scramble on loose rock, with some snow on the last few hundred metres. This may well come littered with human faeces. Yuk.
If you climbing at a sufficient level, the Zmutt Ridge is a far, far better route, with brilliant climbing, incredible positions and scenery, and few climbers. I wrote the AC guidebook description, so I hope it is accurate! To do the Zmutt, you need to be confident moving together on III+ ground, and you should take a few wires and cams as well as slings.
