+ L D B2 R' //RL-EO (4/4)
(U F L2) //2 squares (3/7)
B D B2 U B2 //F2L -3 pieces (5/12)

I have tried so many things on this start, but in the end I couldn't do better than this

CF solve

U2 B' D F' R2 F //CO + pairs (6/6)
D2 B2 L U * D + F' //Corners + 5 edges (6/12)

* = M
+ = [B' U: S'] //3e and skew centers (8/20)

Skeleton:
U2 B' D F' R2 F D2 B2 L U L' R & F @ D' B U D' R' D U'

@ = F2 D2 B2 L B2 D2 F2 R (7/27)
& = M' S2 M S2 (2/29)

Here I was running out of time (hence the x2 in the solution...), but trying some more after the hour I got this:

U2 * B' D F' R2 F //CO (6/6)
D2 B2 L U D //CP -1 move (5/11)
D2 + L' D R L' F' L F2 U' //2 more edges (9/20)

* = S2 //Solves 1 edge (actually solves 2, but un-solves 1) (1/21)
+ = [U' D' B' R2: E'] //Edges and centers (6/27)
