I'm after some quick advice from any London boulderers. I'm working near Chingford today and thinking about getting a training session in this evening. The options are probably Stronghold or Yonder.

Is one or other likely to be better or worse given the crazy hot weather?

Many thanks in advance!

Stronghold is pretty hot in the evenings right now, as its high up (2nd floor) it gets evening sun in the windows. There are fans but no AirCon afaik. 

Yonder by a long shot! They have massively upgraded the passive air conditioning and airflow setup, especially on the ground floor where most of the climbing is.
