In reply to MaranaF:
Rokt have one of their silos dedicated to Figfour, at least they did the last time I was there. I know that they have been used at The Westway, The Castle, Nottingham Climbing Centre, The Cragg, Indy, Dynamic Rock, Foundry, Dart Rock, Redpoint, The Beacon, Undercover Rock.. that list is not definitive but its a start.
