Fastball

Start sitting and bump right, then move up through a powerful match to pinch the crack (left side is on only, no jamming) and toss to the finishing block. Texture/nubbins only for feet, no rock holds. Starting movement reminded the FA of pitching out of a windup

Watch out for the corner of the tower behind you, particularly on the finishing move. I never hit it or felt like I was going to in many sessions of working this, but it might be worth having someone spot you, especially if this is close to your limit
