(U R L' U) //EO (4/4)
(R [c] F2 L' U2 D2 L [e] F') //DR (7/11)
F2 D2 F2 D2 L' U2 //3e3c (6/17)

[e] = U2 B F' L2 B' F (6-2/21)
[c] = R' U R D R' U' R D' (8-3/26)

I had some interesting HTRs from this DR, but I could not get anything better than 26.
The optimal finish (cancelling one with the DR on inverse) was D2 R2 U2 R F2 L F2 D2 U2 L' B2 D2 F2 (13).
This "optimal" (non-cancelling) finish was maybe findable with a sub-optimal HTR: U2 L D2 L' D2 B2 F2 R' U2 B2 U2 F2 L2 (13).
