Guys the sail flake and Perrys Layback are both flakes!!!! You are not going to grind your ass along the rock doing double fist stacks behind the flake while you clip bolts behind your back... that would be retarded. Same goes for Apron Strings the 2 pitch 10- that you can use to start the wall.
The Sword crosses into the realm of technical laybacking, reaching for locks in the thin crack, the last part where it widens is terrible off-fingers and is way easier to layback, and its short so it doesnt really tire you out anyways....
