Around 8a+ to 8b difficulty wise, protected by pegs and small wires. The in-situ gear has changed since the first ascent:
Today, however, the route feels quite different from what Neil, Caff, and Oli would have experienced. Tied-off and equalised bomber pegs now provide the majority of the protection, requiring very little necessary additional gear. Good cams at the bottom and top then cover the pegless sections of rock. [1]
James Taylor re-equipped the route in 2021:
Just a historical note. It has far fewer pegs now than it ever did. I replaced the top cluster of 4 pegs with two new ones and the cluster of 3 pegs that were just below that with 2 new ones. All the old pegs are in my mantlepiece. So 7 pegs were replaced with 4, two pairs of two, this was done in 2021 and now it's common to have the pairs equalised. I didn't replace the 5 lower pegs, 2 of which have now come out. The lower pegs are next to good gear and inconsequential to the route, just artifacts of Twid. [2]
