This is a "direct" start to the Winky Woo, the big, striated, hueco wall left of the Southwest Chimney on the back of the Third Flatiron. Start 50 feet left of the standard Winky Woo where a large pine tree grows near the wall. Work right along a seam, then cruise up and left to a break. Work up and right into good but crispy huecos to surmount the last of the overhanging climbing then amble up the jug-covered slab above. This route can be done in one long pitch, I think.
Take a decent selection of stoppers and TCUs for the lower bit as well as some large cams/tube chocks to protect the huecos through the steepest section. Basically your standard Eldo/Flatirons rack.
