Some route beta. Maybe some of this can get incorporated into the existing routes in the MP.com db already. I'll add the others when I get a chance if nobody beats me to it. I recommend not making up names for problems that don't have established names.
A) "Jumpstart" V3 [5.11]: Lieback up the arete, finishing with a mantel straight over the bulge.
B) (Unnamed) V7(?): Sit start the "Jumpstart" problem. Crux is the move getting into the stand start position
C) (Unnamed) 5.8: Slab climb just right of the arete. Many eliminate the arete (same grade).
D) "Amphitheater Traverse"(?) V2: Traverse the entire S. face of the Amphitheater boulder from Left to Right, starting on problem C and finishing on problem K.
E) (Unnamed) 5.9: Slabby face.
F) (Unnamed) 5.7: Slabby face with big polished edges. Obvious, easiest line on the face.
G) (Unnamed) V0: Slabby face. Start with right hand on slick black crimp. Many variations.
H) (Unnamed) V1: Thin, slabby face. Many variations.
I) (Unnamed) V2: Thin, slabby face. Takes the steepest line through the bulge in the middle of the face. Inobvious and a bit contrived.
J) (Unnamed) V1: Thin, slabby face. Hard start on polished feet.
K) (Unnamed) V1+: Thin, slabby face. High-step start gets harder as dirt erodes. Thicker/stacked pads reduce the grade.
L) (Unnamed) V4: Start squeezing the bulge and pull out left onto the slab.
M) "One Cut Above" V4: Squeeze and slap up the arete to better holds and a rounded topout.
