In reply to james.slater:
I'll back up everthing Alex says about Rock Punk, afterall I'm who he goes with!
Rock Punk is a little gem, Dave the owner is a great guy and the route setting on point, very technical interesing problems. Well worth a session. Can't recomend highly enough if you want to try something different.
Highball is also well worth a visit, just to be fair Mike the owner is a great guy too! They are getting ready to move to a new much larger venue and it can be quite crowded of a evening so day time is better. More of a traditional gym, bouldering focused the rope area is only 7m and not expansive.
Nice thing about both walls is they compliment each other well and are both independent so have their own feel, not corporate megawalls.
Edit: I should have checked the date!
