28, DNF, DNF. 28 was with PDR6 in 8. AB3C in 22. I'll post later.

EDIT
I posted the first line so I could make the deadline.

Here is the 28 solution.

L2 F2 U' L // EO
(F B2 U' B) // PDR6
D2 L2 // 222
R2 F2 // Sq
U R2 D R2 D' U R2 U' R2 U2 // AB3C [22]

L2 F2 U' L D2 L2 R2 F2 U R2 D R2 D' U R2 U' R2 U2 B' U B2 F' [-2 F L B2 L' F' L B2 L']

L2 F2 U' L D2 L2 R2 F2 U R2 D R2 D' U R2 U' R2 U2 B' U B2 L B2 L' F' L B2 L'
