In reply to Stuart_Burbidge:
Don't know about the new wall in Perth.
Avertical World in Dundee is a good 'converted church'. Compared to GCC there's a lot more bouldering but less roped climbing. It's the easiest drive of the centres outside Perth.
The Peak is a few walls in a corner of a sports centre - much smaller.
Ratho is huge, world class for roped climbing, not bad for bouldering and has arguably the best setters in Scotland. The setting and frequent updates make up for lack of bouldering area - still far more than GCC / The Peak, maybe a bit less than Avertical world. Ratho used to be freezing in winter but the roof is fixed now, it has brilliant new lighting and its a fairly mild winter so actually not bad at the moment.
Can't see any reason to go to The Peak or GCC when Avertical World is closer. Ratho is in a different class, but further and if you hit it at the wrong time on a weekday the traffic between the bridge and Ratho can be terrible. TCA in Glasgow should be on the list for occasional visits if bouldering is your thing.
