Eternal Recurrence is the route right of Primeval. Start with a difficult short groove that leads to the big central shelf. Sit down and rest. Then tackle the upper bulge by traversing back left to a very difficult move to the obvious rail. A technical and balancy rockover leads to the final groove and the anchors. I'm not grading this because to me the route is really two roped boulder problems with a sit-down rest in between, the first being V9/10 and the upper being solid V10. Since others may find these sections easier, as happened with Primeval, or find a way around them, as with Shine, I won't be more specific.
(Now that this route has gone five years without a repeat, I am upgrading it to 5.14a in the hope that it will gain more traffic and there will emerge a better consensus on the difficulty/)
