Quite a bit of ice, was rideable but a few sections the ice was right across the trail and the 1st sections of gorse which meant you couldnt ride round it so some careful riding required. The wind was the thing that made things pretty dangerous, if you have ridden the Pentlands in the past with ice/snow and the wind dies down a bit from what it was today you should be fine.
If its as windy tomorrow I would suggest GT as at least you are covered by the trees that way. (It was still fun today, just a bit of a different ride than normal)
