I've been using TCA a fair bit over winter and have had a couple of sessions at bloc now. For what it's worth:
Prefer the setting at bloc so far, more variety of moves. As Duma mentioned they'll need to keep a good team of setters on call to keep it interesting.
Training facilities are a bit lackluster at the moment, woody has potential but needs some smaller holds. Would be nice if they use another one of the back walls as a woody as well. Campus board looks a lot better than the TCA one, can actually get on it when there's other people in the wall. Will be nice when they get some fingerboards up. Bloc circuit board looks a bit shit, corner leaves too much room for technique.
Finding bloc really warm at the minute, think its going to get mega toasty come summer. Bloc is a lot more open than TCA, makes it a lot nicer to climb there as you're not always looking over your shoulder for flying punters.
Both are shit compared to The Climbing Station.
