In reply to Oceanrower:
Okay but as an example this is what I see as the problem., it's not W London but near enough.
High Wycombe (Handy Cross) sports centre has recently had a huge revamp and broadly it has been done exceptionally well. They have the space and the height and they have built some token walls, and outsourced the running to High Sport (I think).
Quite frankly it is turd. It is aimed at kids, parties, and adults who want to 'give it a go', and not at regular climbers at all. I am sure they would dispute this but as an experienced climber who walks past it frequently (to go the pool) that is my strong opinion.
They could easily have done a much better job.
