Hi Andy,
Was there at the weekend. It was a hard slog but good, quite crunchy in places, and slippy in others, didn't have crapons but definately would of been helpful, glad of my poles though as otherwise would have been on my **** a few times on decent. Make sue you have your bearings right at the top, whited out and stuck with compass to get me down. Stunning when clear, take shades, and sun cream if sunny : ) Take something warm if your stopping on top or near for a brew.
Enjoy
Rich
