We got to the bottom of Cneifion Arete (Grade 3) and geared up. I took the first pitch and headed up, got to the stance and then Jess came up and took the second lead. Once on the ridge proper it was time to move together. I started climbing along the ridge placing gear as it was needed, once the rope went tight on Jess she started climbing up behind me. When I finally ran out of gear I belayed Jess up to me and she headed off up the ridge.
