Scramble: R' U' F L D2 R2 U R2 F2 L2 U2 B2 D B' R' D' L2 F U' F2 L' U2 R' U' F
Solution: R' B' U R F' L2 B L2 B' L2 F L2 R' U2 D R' U2 L2 F D2 F' D' B2 R2 U (25)

R' B' U' * D R' //EO + 3 pairs (5/5)
U2 L2 //Square (2/7)
F D2 F' //Square (3/10)
D' B2 //Square (2/12)
R2 U //3e3c (2/14)

* = U2 R F' L2 B L2 B' L2 F L2 R' U2 //Setup + 3 pairs (12-1/25)

You can rewrite the insertion as [U2 R: [F' Rw2 F, L2]]. Optimal insertion, according to IF (select 3c, pure 3c, 3e, 3c3e) :-)
