The 27 move solution found by both me and Michael Young. It was my first full solution (almost linear, I messed up doing the block the first time so I just speedsolved it and rescrambled), found in less than 2 minutes, then I spent 45 minutes checking it over and over again. Michael found it in like 4-5 minutes (I think) and spent the rest of the time checking it as well.
scramble: D L2 R2 U B2 F L B' U B2 R D F2 D' R' U F2 U'
2x2x3: D' R' F' U2 L' F U F2 R2
F2L + OLL: B D B2 D B2 D B R D2 R'
PLL: R D2 R' D2 R F' R' D' R D R F R2 D'
R D2 R' R D2 R' cancels to nothing, resulting in a 27 move solution. Pretty lucky, but given the ease of the first block I think I could have done well either way. Tim Sun found a 5-corner skeleton in 22 moves, and his insertions canceled 5 and 3 moves, resulting in 30.
The funny thing is, for the past two days I had been saying "Well, I'm going to get a 27 on the first scramble..." etc. so now I have been saying that I am going to get 21 on the second scramble
