In reply to tehmarks: As stated before mate nothing on the main part of Sub is affected.
There are two main areas of the cliff and both are accessed by separate abs in (one down high st, and one down freda).You can get all the way along the ledge, but in some places the gaps are large and feel a bit spicy! (don't feel coy about roping up for some, I think at some stage we've all done it).
Subject to the weather the best thing to do is ab into the High Street area (which will give you a feel for Sub but in a nice safe and cosy way (with an easy route out - High st).
I would suggest High Street as a first climb (although its only a diff it's a magic route and will give you an idea what's ahead - and if it was anywhere else it would be VD).
Another good route nearby is Gangway (couple of tricky moves off the deck but then easy with loads of gear.
Some of the cliff can stay wet for quite a while after rain, and I would suggest that you stay off the wet/damp stuff as it's really dangerous.
But enjoy (and make sure you double check before you abb in (as its very easy to go into the wrong place - and sometimes hard to get out)
Enjoy
