In reply to THE.WALRUS:
Just to put your thread back up top again in order to hear the answer for myself.
We were in Snowdonia last weekend and one of my friends fancied the direct HVS route at Cwm Silyn,but we decided not to go as we remembered about the rockfall.Instead we climbed in the pass in the wind and sun.It was a brilliant place when I climbed there in the past,so I hope that it is going to be feasible again in the future.
