In reply to Tom Gape 2:
Bristol could do with a modern lead wall. My wish list:
Make it a higher version of TCA, or The Works: flat panels, rather than "featured" stuff. Build interest by using modular volumes. "Artificial rock" is a gimmick that would soon feel tired and dated.
High, and gently overhanging.
Use pro route setters, and change routes regularly and often. Limit the steep jug-fests. The routes are the product you sell. Many potentially nice centres fail by trying to save on their route setting. Publish your routes online, and encourage people to comment and discuss grades. Grade your routes consistently. It can be done.
Make it a credible place for good climbers to train - no (or limited, at least) kiddie parties, proper training features (systems boards, campus area etc). If you pander to the "F6a" majority it becomes a self-fulfilling prophesy - encourage people to improve.
Run regular competitions - it's a great way to build a community.
Run it with staff who are climbers - for climbers by climbers, rather than as a leisure centre.
Listen to customer feedback. Keep the centre clean (including toilets!) and bright.
Make it cool in the summer, and warm enough in the winter. Invest in proper air conditioning, not just fans.
