Thanks to a very nice video
I got some nice hints in your video.
And.. I will tell you my tricks about your video.
2:40 - if I have this situation, I will do (D' R' F R F Rw' F2 Rw F2 U' Lw' U Lw) instead of (R' ~~) because I hate that my targets are located on the back.
But your solution is good, too. What I want to say is that ( Rw' F2 Rw F2 U' Lw' U Lw ) is pretty good.
And if I do (R' D')(like you), my next move will be (R' U' R [R3 U2 R3'] U' M' U M).
3:10 - is ( L M' U' M L' ) better than your solution? or ( L U2 L' M' U M )
I think that if you reduce moves , you can get more faster!
3:15 - This is my favorite case, if I have this case, I will do ( F , do not L) and locate green middle centre on l (small L) line, and do ( Lw F Lw' ) then I have 2x2x3 centres!
7:23 - This case is not bad, try ( F' U F' U R3 U' R3' Rw U' Rw').
8:05 - I made nice solution for this case two months ago, that is ( Rw2 U R U' Rw2 ) ( working for 4x4!! )
8:17 - ( D' R' D' U2 )
12:20 - ( R U R3 U R3' ) Then you can get the last cross edge on easy position.
So... I hope that my tricks can help you.
And thanks for reading my terrible English...! actually, I couldn't understand your say in video because my English listening is also bad.. orz.
