I asked locally the other year about srt, but the outdoor centre here only does abseiling.
Funnily enough it was because I'd been reading up on getting into Moel Fferna, but you mentioned in your recent thread that it could be a possible scramble to access/exit it?
...Oh yes, and I aquired a small but perfectly formed Electron type ladder last year too.
(Dunno if I'll ever use it though.)
Apart from that, I'm not really into climbing though.
