All on inverse (too hard to type without my laptop)

R D2 F2 L//EO
B' (B2 U2 R2 F' R2 F')//DR,11+2
(R2 B2 U' L2 D')//HTR
U2 F2 L2 F2 B2//Leave slice in 21

Solve the slice in +2 orz.

I had some promising stuffs from the 8+4 but I messed up.

(U' F L2 D)//EO
(U2 F L2 B)//8+4, 21 opt

D' R U2 F'//EO
(R' L2 D F2 U L')//DR,10+3Q4C4E
(F2 U') D' R2 D//HTR
F2 R2 F2 L2 B2 D2 F2//leave slice in 22

solve in 23

I didn't have anything until 40 minutes. Hard scramble IMO.

L2 D' B' U//EO
R B2 L2 D2 R U'//10+3
R F2 R' (F2 U2 F2 U2 L)//htr
(B2 R2 D2 F2 D2 B2)//leave slice in 24

solve e slice in panic to get 30

B' F2 L' D'//EO
F' B R F2 R' F2 R'//DR, 11+2
(B' R2 B)//HTR lol
D2 B2 D2 R2 B2 U2 L2// Finish in 21

Lucky finish but not too surprised considering the huge amount of variations there. Findable optimal is 20 by DR-flipping.

The only other promising DR i have: (B F U' R   D) L2 U2 B' F2 U which is 10+3q4c

 F' (L2 F')//EO
D //DR-8e8c
B2 R' U' D  //DR, 8+2
(D2 B2 [L2 U2 R' D2 R F2 D2 L2] F2)//19 TO SLICE !!!!!

[] ---> L' R' F2 R' B2 R D2 B2 R L//solve in 21,sad
