In reply to ExiledScot:
I once headed up there one day when there was about a couple of Cm of snow. There was no point in putting crampons on, so I just used a single axe. I sort of scrambled/rock climbed until just beyond half way, when a more definite thin layer of ice was found on a large block with no real crack purchase for the axe. I felt that I could get up it, yet there was a chance of slipping backwards/falling if the thin ice gave way, and the exposed rock was wet and greasy.
I decided that if I did fall, then I may be in real trouble as I had no phone signal, and was on my own. So I downclimbed the whole lot with difficulty (I had no rope, as I had originally set out to just do winter fellwalking).
So that could be the sort of experience that you get if you go there.
