1. in-limit=27 
(B2 R' D2 F' R2 D') // 6/6 222, between the F' and D' I tried Rn and R2 was best for me
F' R U R2 U2 // 5/11 333
F' U F U' // 4/15 EO; starting with F led to L5C in 22, with F2 to L4C in 21
R' F' R' F' // 4/19 L5C
ssf: F' R U * R2 U2 F' U F U' # R' F' R' F' D R2 F D2 R B2
* U' L2 U R2 U' L2 U R2 // 8-5/22
