In reply to foxjerk:
You can't really compare the two. Clashot is a dedicated climbing wall with lead routes, decent route lenghts and bouldering etc.
The Edge is basically a couple of top rope panels at the back wall of a multipurpose gym hall.
That said: If youre looking for a climbing wall in the Wimborne area for a couple of sessions is's pretty decent.
I heard the boldering room upstairs has improved and is supposed to have some interesting problems.
If you have the choice between Calshot and the Edge, go for Calshot. If the Edge is your only option it makes for a decent session
