Aid

I climbed a little aid line up at Twin Towers. It starts between the Offwidth and Cloud Nine, and finishes at the first anchors on Cloud Nine. I used a blue TCU, knife blades, rurps and a hook. Its maybe A2 and very short at 8-10m high. Be warned a fall from the hook at the top would send you on a long fall as the rurps ripped out. Close if not on the ground.
Have fun
