A Useful OLL (Inserted) by Sebastiano Tronto

Scramble: L2 D2 F2 U’ L2 D L2 D2 B2 U’ F’ U’ R’ D B2 L D B’ F’ R’
Solution: F2 U R’ U’ F D2 F R F D F2 R F R2 D R D2 R’ F2 U2 R D R’ D2 B2 R2 (26 HTM)

Explanation:
Premove: R2
F2 U R’ U’ F D2 * F’ U2 //2x2x3 (8/8)
R D R’ D2 B2 //F2L (All but 5 pieces) (5/13)
R2 //Undo premoves (1/14)
* = (F R) F D F2 R F R2 D R D2 (R’ F’) //Last 5 pieces, one move cancels (12/26)

Comment:
The insertion is a 2-moves setup + the LL alg F D F2 R F R2 D R D2, which is the shortest algorithm that only affect the orientation of some pieces (5, in this case) without permuting them.
