Next: I just got a good time on this- F' R D' L R U' B' U' R D' U' B2 L U L2 B F U2 F' R F R F2 L2 R
EOLine: B U2 D' L2 B L' D (Okay, I guess. I must suck at getting near-optimal EOlines, though, because I almost never get 7-moves ones)
1st Block: R' L' U2 R' U' R'
2nd Block: L' U L' U L U2 L U L2
1st Pair: U2 R' U R U' L' U2 L
2nd Pair + Partial corner control: R' U' R U2 R' U2 R
V-Perm: U R' U R' U' y R' F' R2 U' R' U R' F R F U2
A pretty good solve, although 53 moves is surprisingly high for a forced OLL skip. That OLL skip, btw, is why there's a U2 before the insertion of the second pair. For the first pair, a U2 insertion was put there to separate a misconnected pair that was already in the slot.
Next: L' U' F R2 L' B2 R' F U' L2 D F2 B2 R2 L' B' L F' R' F' R D R' D' U2
