Three I've just thought of:
The rock humper after the right hander at the east end of Sticks and Stones. I might be 1 in 3 on that. For a while I was better than 1 in 2, but that didn't last long.
From the BP pipeline bridge up to Fishermans at Riverside. Less than 50%, but improving since getting a big long 29er under me.
Applicator from Cardiac Bypass to Rapid Transit. High line is somewhere around a root with a rutted out rocky bit next to it :lol:
