Underminer v10

A climb that is notoriously done differently from how it was originally climbed. Originally done as a sit start with both hands outside of the overhang on the right arete with sidepulls/slopers. Any deviation from that start lowers the difficulty. Hard compression through fins, slopers and gastons in the overhang take you through the engaging mantle. Kneebars helpful.

Without a kneepad. Pants ripped second go and only had about 4 more attempts of skin. Luckily sent on the 5th. Might try it again with the proper beta. This way even without knee pads is probably soft 10.

Extremely soft, I could see a downgrade to V8

Knee bar compression, it is the only thing i can climb really. Soft and/or my style i can't tell anymore. Fun Bloc with funky moves!
