In reply to BnB:
I was on Bristly Ridge on Saturday with two clients. Sinister Gully (the gully denoted as the start in Scrambling in Snowdonia guidebook) had plenty of snow in it. There's also some big patches of snow on the ridge especially from Great Pinnacle gap. Definitely wasn't bare and with it being a bit colder now I would imagine the snow has firmed up so would definitely recommend crampons and an axe.
In Cwm Cneifion, Easy Route at the back headwall was complete, bit of a slumped cornice at the top on the left with a slot cut in but steep to go through, heading right of cornice may be better option? We did Hidden Gully right hand finish which is about grade II/III. It had a little bit of ice to get into the right hand finish, the gully was then firm neve and dry rock at the crux with some good runners. Hidden Gully normal finish was well banked out. But don't let me ruin the adventure for you...!
