I thought the first pitch of Nutcracker was the hardest, but that was before I knew how to jam. Actually, we saw a guy take a spine-chilling fall on the left line start, with the long lieback. He liebacked really high, then buttered off when he finally decided to try placing some pro. The tree caught him, and he walked away bloody but generally okay. I'm scared of liebacks ever since.
So we did the right/center line start, kind of a 5.9 finger crack.
