Grinding on a Sick Rail

On the middle face of the Chimney Boulder, stand start with a left-hand sidepull and a high right-hand flake with poor feet in the horizontal crack. Go straight up to a small crimp shelf (very sharp!!!), and go straight up for topout. This has a less-than-ideal landing but a good topout.This is a very unofficial grading on this one, would really like to get other people's opinions on it!
