In reply to royal:
"Gaz Perry" - sorry, who is he? I know of a chap by the name of Gareth Parry who is pretty reasonable and I've enjoyed climbing with a few times.
Price: even with Steve and Gaz rubbing my aching feet and setting routes of my choosing on request, any wall that charges £12 for a member entry is overpriced. Period.
Routes/accuracy of grades: I've climbed all the main lead lines in the building up to "8a" (7b at max. in actuality) mostly onsight and I'd quite honestly say they're a numeric French grade too high as a rule of thumb. Get clipping some bolts in France if you don't believe me - it might give you a bit of a shock.
Rubbish: The thing I actually dislike though are the obvious safety issues predicated by the wandering lines. This worries me less on the lead lines where (hopefully) people have some idea of what they're doing, though it's obviously a pain to have to wait for someone to spin off a whole lead before you can climb as they're climbing on both yours and their line owing to the setting. However, it does cause me concern on the novice lines. For example, last night my girlfriend was toproping a 5+ where, at one point, she was literally 5 metres off to the right from the belay point and looking at a bloody massive swing into another girl climbing the adjacent route. I just don't get it; what's the point!?
And before you say it, yeah I have spoken to the staff about it.
