In reply to Misha:
I have done many of the classics on the Cromlech either just after rain or actually raining, but this was in PAs in the days before sticky rubber that seems to behave differently.
Cenotaph Corner, after a night of heavy rain, we gave it a couple of hours to dry off a bit.
Cobweb crack similar
Ivy Sepulchre it rained the day before.
Left wall it rained the day before.
The Gates will not be affected apart from the start of second pitch maybe.
If it is clean, it is climbable. I was a tad unpopular with our team when I did Kaisergebirge wall as it was raining hard, it was fairly sheltered on the climb but they were getting very wet at the bottom, and I had the car keys. They threw clods of earth and pebbles at me to come down, no chance after doing the crux.
The Mot is a different matter, you need to pick your routes carefully on there after rain, so Mole, Plexus and Maybe Nexus are the cleanest HVS+ routes up there.
