Strap some rubber on your left leg, climb the Youth Warm-up to the big jug ledge at the last bolt, don't clip it, clip right instead, and head up and right straight into the crux kneebar. If you don't like this technical kneebar, buck up, and dispatch a large-ish dyno instead. Either way, hang on through a rightward-trending rail-type feature to some easier very fun crimpy, edges (12a ish) to the top.

This is not classic but a pretty fun one nonetheless. The grade will be quite subjective. It's probably a bit morpho.

Update: New beta has been discovered, bypassing the knee or dyno beta, look for a left hand pinch up and left coming out of the big hueco. This will likely bring the grade down a notch or two.
