A few example solves:

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

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

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

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.

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

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
