I'm curious to compare some different approaches (M2, TuRBo, BH, etc.) for the following position:
Please show your method for solving these edges -

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]

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

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'

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.
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: 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>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
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 favorite cases. If anyone has something they think is faster, please share.
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

BH:
x' y [L2, U' M U] y' x
z [U' R' U, M] z'
x y' [U L2 U', M] y x'
x [R2, U M2 U'] x'
x' r R U R' U' r' U2 R U R U' R2 U2 (x)
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.

Is there something about your method that makes it hard to take advantage of easy 2x2-cycles?

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.
