Tim Carruthers has added a neat full traverse of the Medium Ball Boulder at Carrock Fell (page 512 in the guidebook).
Homage to Catalonia (6C), starts sitting on the block on the extreme LH end of the left face of the boulder and traverse the entire boulder to a low finish on the block on the right. The drop-down move from the two good crimps on the front face into the big starting hold of Medium Ball is excellent and the crux is at the end. An alternative finish links the traverse into the new problem up the rib to the right of Medium Ball.
