Up to #4 Camalot with extra .5 and .75. Probably get away with up to #3.
Start up a massive right facing corner to the left of Airbourne, Atom Smasher, Massive Attack, etc. Climb the corner crack using jams and liebacks until you can traverse out to the arete avoiding the roof. Face climb the arete to anchors.
Variation: Pull straight through the roof on great gear and fingerlocks. This way is thought to be 10+ and is a much cleaner and direct line.
