Low Blow

Sit start in the middle of the block. Find a hollow sounding flake that has a tiny incut crimp rail on top of it. Above that and to the right will be an uneven crimp rail for your right hand.

Place feet on whatever and either bump up to an intermediate crimp, or just move big up and left to a tiny gaston crimp.

Continue through better territory to the top out that is the same as Arthur's.
