A few example solves:

R U' L2 D' F2 D' U' F D2 L D2 F2 D' B L' R F' R' U L F2 B R B2 R'

F2 L R' U' R //Elayer
R U R' U R U2 R' z2 F R U R' U' R U R' U' F' //Orient C
F2 U' F2 U R U R' F' R U R' U' R' F R2 U' R' //Permute C (I'm working on the cornersteps currently)
U M U2 M2 U M D' U' M2 U2 M2 //Dlayer
M U' M' U2 M U' M' //Orient E
U-perm
D' R2 U' R D' B' R2 L' F2 U' L2 F L2 R2 U B2 R2 L F B R B L D' L2

D2 R2 D x' L U2 L' //E-layer
R' U' R U' R' U2 R U2 L' y' R U R' U' F//Orient corners
U2 L2 U D L2 D L2 D' L2 //Separate
x2 R2 U R2 U' R2 U R2 U R2 U2 R2 //Permute
U' M U2 M' D' M U2 M' U' M' U M y' M' U2 M //D
M U' M' U2 M U' M' //Orient
H-perm
R2 L' D2 F2 L2 D B2 L U2 R2 D L' F' R2 F' B R' D U2 B2 F2 L' D2 U L'

L U' L R2 F' U' F //E
R2 U' F R U R' U' F' x2 F R U R' U' F' //Orient
U D2 R2 D' R2 U2 R2 //Separate
U2 R U R' F' R U R' U' R' F R2 U' R' //Permute
M U2 M' U' M' U' M y' U M' U2 M U M U M' //D-layer

All are Alg garron checked

Another idea:

1: E layer
2. Orient all corners
3. Permute bottom layer corners
4. Place D layer edges
5. Orient edges (Basically 3 OLL's since all corners are oriented)
6. PLL

Steps 5 and 6 could probably be done together, I just don't know any alg set that permutes corners and orients and permutes edges... Anyone?

One more:

1: E layer
2. Orient all corners
3. Permute bottom layer corners
4. Place 3 D layer edges
5. L5EOP
6. PLL

Is it not a lot more efficient to orient edges while placing the E edges? It is also much better use of inspection time.

I'm not sure how you intend to deal with corner parity, which is a big deal for any kind of "C*LL twice" step. This method relies heavily on algorithmic steps without really providing any good lookahead opportunities or turning freedom. I think knowing full CLL and ELL may make this method look better than it is, and you won't have too much difficulty getting to a decent average (sub-20?) but you will find it very difficult to get really fast times.

Yes, I'll try that

1. EOBelt
2. Orient corners
3. Permute Bottom Corners
4. Place Bottom edges
5. PLL

I still don't think this is good for anything else than fun solving, but it's definite possible to sub 25, maybe even sub 20 with it

You also can do step 3+4 together (it's very intuitive, just using U,D,R2):
1. EOBelt
2. Orient corners
3. Solve D-Layer
4. PLL

The only step I have problems with is 2) Orient Corners. What is your method for that?

Maybe solve parity + 1 alg would be good?

First try. Seems too long (79 STM). What do I do wrong?

Okay, here is another one:

R2 B2 L2 U F2 U' B2 U' F2 R F D U' B D2 U' F L' D'

B' R2 B2 L2 U' L // belt
F2 U2 F2 // phasing
D' R2 L' U' L U' L' U2 L U2 R2 // CO1
R' D' R D' R' D2 R // CO2
y2 U R2 U' R2' U2' y R2 U' R2' // CP
D' U' M' U2 M M U2 M' y U' M' U M // down edges
M U' M' U2 M U' M' // EO
U' M2 U M U2 M' U M2 // U-perm

59 STM.

Well, you are understand about ECDU method, second solve is a very good examble, you can reduce more movecount by directly using ELL. At a first solve you wasted your move in two times phasing and you met parity, so it's too long.

Note: I would very happy if you use "equator" replace for "belt" :D
