Doomsday Device

On the South Face of the Magnificent Bastard, Scramble on top of a boulder and get your pad and spotter ready below a scoop leading to a tips crack up a slab. Climb up the scoop and into the Tips crack until it runs out. Do a fun couple of face moves to the lip.
The rock quality is good, but the loose block where the crack runs out makes this problem a serious undertaking.

South face of the MGB.

Pad and a really good spotter.
BEWARE: Where the tips crack runs out there is a gigantic dislodged block. While I doubt it is going to fall, and you don't need to pull on it at all, it is a severe danger factor in an already dangerous boulder problem. The landing is bad, and if you fall it is necessary for your spotter to keep you on the boulder where your pad is.
