In reply to chubbs2:
Climb Rochdale does not deserve the negative review above. I visited that wall last week for the first time and found a range of decent problems, particularly in the main area. Some really interesting ones too. Perhaps the best problems were in the v4 to v7 range.
For the last 5 years I have taken a small group of students around the north west and therefore know the competition pretty well. They all have their strengths. There were certainly no kids running around at Rochdale last week, and if there were then at any wall, then SIMPLY tell the staff.
Boulder UK makes the best of its building. Problem setting is obviously excellent. The main room is good, but the other rooms have disappoitingly short walls. Personally I would choose Rochdale over BoulderUK. It has a decent system board too.
Preston is worth a visit for bouldering.
Awesome Walls Stockport is a great wall for climbing and bouldering.
RockOver is decent, with massive potential, but has dropped in my estimation in recent visits. The central area has good problems, but other areas seemed a bit lacking in inspiration.
Personally I don't like the move some walls have made to using colour tag on start hold rather than grading for hold colours. I know why they do it, but it results in a less satisfying session for me. Makes finding decent problem at a certain grade range more time consuming.
