Between Weed Killer and Sardine
Paxo E6 6b takes any start to belay at the top of Weed Killer. Clip the 1st and 2nd bolts of Rooster Booster then step down. Move right and go up a groove to a break. Traverse right along a break and go up a groove to a break. Abseil off.
Hope this helps. If you want a scan of the guidebook page, pm me or leave a message on this thread.
