Clip the bolt before pulling pulling the first bulge. Tricky is putting it mildly. Get your feet set, use the left hand side pull at the top of the seam almost directly below the first bolt. Reach up, grab the crimp with your right hand, and slap your way up the big sloper feature on the left. Climb the face and reach the bulge. Use a right handed, 2 finger pocket and perform a hard sidepull while getting your feet high to reach a decent left handed edge. Crank through and climb a short face to reach an anchor.
