What is the hardest boulder problem in Scotland at the moment? Here, Malcolm Smith repeats his mighty, extended "Gutbuster" font 8b+ at Dumbarton. We filmed this the day after Malcolm completed this epic. It was amazing editing his move-by-move commentary onto the film of him climbing - his words followed the cadence of the moves almost exactly to the beat! One day soon, I hope we can bring you news of the first ascent of his long-standing project at Dumby, very likely to be Scotland's first font 8c. Go MALC!
