This route is listed in the Kelman gb as 5.7, but I personally thought it was harder than Handjacker. Difficulty really depends on which side of your body is in the crack.
Start 15ft right Lower Progressive and find a wide crack just before the rock rounds the corner and heads towards Escalator.
Pull off the ground through the crux start to get situated in the crack that widens into a chimney. Wiggle up to the ledge for the start of Escalator and downclimb the chimney approach for that route or rappel from anchors above Lower Progressive.

Big Big Bros would work but the better plan would probably be to put down a crash pad and boulder it.
