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.
The first time I bouldered this route was in the early '90s and am pretty sure I wasn't the first person to do so. I don't know how anyone would think that such an obvious line, located right next to Progressive would have been unclimbed as late as 2002. It isn't really worth roping up for as it is really short, with the only hard part right at the ground. In my opinion, Handjacker is a much better route at a slightly harder grade.
