Because I can. Clean aid is awesome, and it is not a straight forward C1 line. I guess I am not a Masteraider like you. I don't lead 5.10b free. Go for that lead if you want, it looks really thin to me. I was looking at it real close. I have to practice somewhere and Jim Opdycke told me it was a good one for that. I did the first part in a full on rainstorm and Tuesday it was blowing about 30 mph. Great weather for aid. Merry Christmas!
