In reply to The Ex-Engineer:
Thanks for the reply, but I think maybe it's changed since then.
We were planning on doing the classic route (I think that's the same as the pierre-allain?) in 2012 but the lads at the ohm warned us off because there'd been a huge rockfall the week before, and they seemed to think the whole N face was very unstable. I think there've been a few more since, but maybe more on the W face.
I was wondering if anyone had done it in the last couple of years?
