I'm curious to compare some different approaches (M2, TuRBo, BH, etc.) for the following position:

Scramble: D U R2 D2 L' D U' R B L U2 R' U' L' F

[cube]&size=150&pzl3&alg=DUR2D2L'DU'RBLU2R'U'L'F" [/cube]

M2:
DF>UB: M2
DF>FU: D M’ U R2 U’ M U R2 U’ D’ M2
DF>UF: U2 M' U2 M'
DF>BU: x' U' R U x U R2 U' (M2) U R2 U' x' U' R' U x
DF>FL: U' L' U (M2) U' L U
DF>LB: x' L' U L U' (M2) U L' U' L x
DF>LF: x' U L2 U' (M2) U L2 U' x
DF>BR: U R' U' (M2) U R U'
DF>FR: U R U' (M2) U R' U'
DF>RB: x' R U' R' U (M2) U' R U R' x
Flip UR: F2 (R' U2 R2 U R' U' R' U2 Rw U R U' Rw') F2

TuRBo:
UF>BU>DB: x' U' L R' x (U' R U R' U' M' U R U' Rw' U) x' R L' U x
UF>FR>RB: R Bw (U' Rw U R' U' M U R U' R' U) Bw' R'
UF>RF>LF: R L' (M U' M' U2 M U' M') L R'
UF>BL>FL: L' Bw' (M U M' U2 M U M') Bw L
Flip UR: R' U2 R2 U R' U' R' U2 Rw U R U' Rw'

3style:
UF>BU>DB: x' U' Rw R' (U' R U R' U' M' U R U' Rw' U) R Rw' U x - This is one of my least favourite cases. If anyone has something they think is faster, please share.
UF>FR>RB: R U' R' E' R U R' E
UF>RF>LF: x U2 (R2 U R U R' U' R' U' R' U R') U2 x'
UF>BL>FL: x' U' M' U L2 U' M U L2 x
Flip UR: R' U2 R2 U R' U' R' U2 Rw U R U' Rw'

If you're going to scramble in that orientation, so will I.

3style:
x2 U' R2 U' M U R2 U' M' U2
y z L' U M' U' L U M U' z'
x M U M' U2 M U M' x'
z' U2 M' U' R U M U' R' U' z
x' U' M U2 M' U' x

B2 R2 B M2 B' R2 B M2 B

I scrambled in my solving orientation. Solved 3style.

Flip UR: U x M' U M' U M' U M' U2 M' U M' U M' U M' x' U'
DF>UB>BD: x' F U R U' M U R' U' M' F' x
DF>UF>BU: y' R2 U' M' U R2 U' M U y
DF>FR>RB: z' U' R U M U' R' U M' z
DF>RF>LB: z' M' U R U' M2 U R' U' M' z
DF>LF>BL: z M' U' L' U M U' L U z'

I'm not sure if you'll find this faster but this is what I would do:

y U2 R2 U' M' U R2 U' M U' y'

@all, thanks for the solves - they are all very interesting to me.

UF>BU>DB is [CQW]: [F:URU',M] is faster

re: D U R2 D2 L' D U' R B L U2 R' U' L' F

[CQWi]: FURU'MUR'U'M'F'
[Jt.Lr]: R2E2R2E2
[birt]: xy (U'R) (M'U')4 (R'U)

Because this was a very easy edge case, I didn't need to memo and did the following
y2
R2 E2 R2 E2
D U R2 U' M' U R2 U' M D'
X' D' L' (M U')*4 L D

Also for Zane
I like x' D M' U R2 U' M U R2 U' D' x
You probably already know this alg, but rotations can make everyone lose some good algorithms

Thanks riffz, reThinking the Cube and Lemon for the suggested algs.
I'm going to choose this, it's the fastest and most intuitive approach for me.

x' y [L2, U' M U] y' x

that is elegant! your buffer is different than mine [C v. A] nice.

@3-stylers (chrishardw,aronpm,riffz)

Noted: fearless cube rotations to get better algs, with no sign of the seasickness that would be expected from trying to keep track of a blindfold buffer that is hoping around like a flea on a hot skillet. So it baffles me more than a blown transmission on a 1970 Maytag, that you avoided the rather obvious shortcut (R2 E2 R2 E2), and wasted a lot of time by 3-cycle shooting this permutation.

As someone who is actually fast at BLD, and has gotten cases like this in solves, I would say that the extra time to think about the different solution makes the solve slower. It's the same reason why I would not do an R2 premove to solve a 1x2x2 block in a BLD solve: it complicates memo and execution and just slows down the automatic solving process. However, that's not to say that just simply z'U2M2U2M2z, or a H/Z perm would not be something I would do. Doing that and then doing edge flips is a hassle.
