Hayden and I once again roped up together for the reg on Half Dome in Septmeber. We were shooting for a time of 3:30 or less. This time we switched blocks to try something new and I led the first 17 pitches while Hayden simuled under me. He led the last 7 or so pitches shortfixing but we soon realized our rope was about 25 m long, a little too short. We got hung up in the zig zags unable to lead after fixing the rope due to our short rope. Oh well, we still smoked the route in the 3:27. everything went smoothly and we were back at the lodge spraying to our friends before 3 pm!
