For my part, the Helsinki university's campus climbing wall is now checked out. Today, I had a couple-hour climbing session there and it seemed to be a quite small place, but still interesting and cosy for indoor climbing.
The routes seemed to be a bit more technical than strength demanding, so even in some 5a's, a smaller guy had to reach for the next holds with more technical body positions. The final "score" of the day were a few 5c's, which actually seemed to be easier than some 5a's.
Any way, a fairly good place to practice climbing technique and remember to climb rather at noon, so the place won't be totally crowded.
