Use the horizontal, angling crack and/or the vertical crack to the right to surmount the small roof. Follow the bolts up and slightly right, staying on the slight prow between the crack/flake systems to get full value from the climb. Moving either right or left into the weaknesses makes the route noticeably easier (booo!), and never mind that runout between bolts 3 and 4 - the climbing is not that hard and the hardest moves are just past bolt 3. Continue up on better holds, and finish up and left at the first big roof.
