(R U R2′) (F’ U’ F U) (R2 U2′ R’) (W shape stuck to left back corner)
(R U’ R’ U’) F (U R U’ R’) F’ (R U2′ R’) (W shape stuck to front right corner)
Although the second one has more moves than the first, I can turn the both in almost same amount of time. This may be because I turn R U’ R’ sequence slightly faster than R U R’.
