With needing to rope? North ridge of Tryfan followed by bristly ridge..
or make a step up and do Dolmen ridge.. Dolmen is easy but has one nasty pitch.. its 2/3 I think, but for some reason the pitch hit me and I had to lead it as a pitch.. once you took it seriously it was simple climbing, but we were expecting to move together, almost running up the route..
