(L F U D' R') //EO (5/5)

(U F' U') //DR (3/12)
(L2 B2 R2) //321 (3/15)
(D2 B' U2) //Square + pair (3/18)
(B' D2 F' * D2 B2) //3c (5/23)

Solution: U B' R' U' B' L2 U F' B L2 R2 F' D B' D' L R U2 L R' U2 F2 U' F2 U (25)

U B' R' //EO (3/3)
U' B' //Simplify 3-1 (2/5)
L2 U' D2 [x] //Setup (3/8)
B' U B' //DR (3/11)
U' R2 [e] F2 D2 F2 D F2 D2 //3e4x (8/19)

[e] = R' L D2 R L' F2 (6-3/22)
[x] = U2 D2 B F' L2 R2 B F' z2 (8-5/25)

I also had this skeleton with HTR in 15 (one of my first HTRs in an actual attempt):

U B' R'
U' B' L2 U' D2 B' U B' //Same DR
U (U' F2 U') //HTR
L2 B2 U2 L2 B2 D2 //2e2e in 21

But it does not give anything better than 25.

30, 27, 25 = 27.3
