    Aron, good work on finishing the page, it looks good. I'd been on your site earlier on and had learnt a few, now thats its complete I'l try and get through more of it.

    Recognition is faster than recognition of PLLs when you are used to it(I basically know the place of remaining cubies after step 1, and what is needed only the orientation of 1 corner)
    Step 2 requires a lot of moves, but can be done around 1.5 sec with speed optimal algorithms.
    There are many ways to reduce the number of cases in step 1(or skip it).

    "step 2/2 will require one more algorithm than simply OLL/PLL" <= what do you mean?

    What's th probability for a random LL case to be 22LL? ... quite low I suppose?

    More difficult might be the question: how much can it be increased be doing some trivial Last-Slot modifications? (partial edgecontrol / partial corner control)

    Anyone suggesting this as a last layer method needs to read Athefre's post.

    Once you have read that you can start working on a system that will solve this problem. Then you can tell us how to do CLL+1 easily, too.

    So, finally getting some time to have a look at this and learn some. I'm learning by PLL sets, and I'm not learning all of it. I don't see why I should, I can setup to one of a few PLL shapes easily then solve any orientation of the pieces within that shape. I decided to use T, Jb, Rb and Y. I didn't like some of the algs, so I made what I believe to be better ones for some cases, sometimes copying/modifying the ones from the site. Here's my full alg list for what I'm learning, bear in mind that it's not in Aron's notation, but by edge orientation and the "shape" of the corner orientation. Also that I sometimes do crazy stuff like R3 :p, adjust to your style as necessary.

    PLL: R U R' U' R' F R2 U' R' U' R U R' F'
    T: r' U r' U2 R B' R' U2 r2 B'
    U: U R' z R2 U R' U' D R D' R2' U R' D R3 U'
    Flip: R2 B' R' B R' F' U' F R U R' U'
    T Flip: F U R' U' R D' R2 U R' U' R2 D F'
    U Flip: r' R2 U' R' U F' r U' L' U2 L R2 F R F' U'

    PLL: R U R' F' R U R' U' R' F R2 U' R' U'
    T: r U R2' F R F' R U2' r' U r U r'
    U: F2 R' F R2 U' R' U' R U R' F' R U R' U' F2
    Flip: R r U R' U l' U2 L F' R U2 r2' F2
    T Flip: R U2 R' U' F' U R U R' U' R' F R2 U' R' U2
    U Flip: r' R U R U' L U L' U R' U' r B2 R B2 R2'

    PLL: R' U2 R' D' R U' R' D R U R U' R' U' R U'
    T: R U2 R' U' R' F R2 U' R' U' R U R' F' R U' R'
    U: U R U' L U L' U R' U' L2' R' F2 l D2 L r
    Flip: L2 l' U' R U2' L' U R' U' R r B2 r2'
    T Flip: R U R' U R U2' B' R' U' R U B U' R' U2
    U Flip: R' F U' F R' F' R2 U' R' U2 r U' r' F' R

    PLL: F R' F R2 U' R' U' R U R' F' R U R' U' F'
    L1: U r U2' R2' F R F' R U2' r'
    L2: l' U L2 F' L' F L' U2 l U'
    Flip: R2 U R2' F' U F R F' U' F R2 U R U' R' U' R2
    L1 Flip: M' U L' U' L r U2 R' F' R U2 R r2
    L2 Flip: R' U' R U' B2 r' U' r B2 R' U' R U B

    Enjoy :)


    Edit: Fixed some and improved some, still a couple I don't like (Y flip, T U) but I'll work on it.
