New Simple 3LLL "Fork Last Layer" method = smart 2-look OLL + CPLL (4 alg)

Hello all! After all 4LLL method and all 3LLL methods (2look OLL+PLL, LLEF/OCLL-EPP/CPLL (BLL), EOLL/СOLL/CPLL) i compile own simple 3-look layer (3LLL) method with fast recognition and simple algs (only 8 original algs, other 20 algs with sexy, Sune variation).
I named it Fork Last Layer (FLL), and develop full description (see attach). There is block-scheme.
Key technology this method - is EFLL substep - enhanced EOLL method for Dot, L-shape and Line (much easier, than LLEF) and i found many algs for OCLL with swapping 2 edges (i named is OCLL-OES ).
I found this method for myself, because the full PLL algorithms are too long and complex for my fingers (and my best 4LLL algs was 2-look LLEF+2-look L4C).

Edge Fork - is double state - 50% solving Edge and 50% solving with 2 opposite Edge Permutation.
EFLL - Edge Fork of the Last Layer
OCLL-EFP - Orient Corners of the Last Layer - Edge Fork Permutation
OCLL-EPP - Orient Corners of the Last Layer - Edge Permutation Preserved
OCLL- OES - Orient Corners of the Last Layer - Opposite Edge Swap

FLL pro:
  • Simple finger tricks (only 8 original algs, other 20 algs consist fast «sexy» and Sune variations);
  • Simple recognition for all 3 steps;
  • In 2/3 cases CPLL has short (9 moves) algorithms (A-perms);
  • 1/12 probability CPLL skip.
FLL cons:
  • Cannot be extended to 2-look method;
  • For Cross with adjacent color cases not have 2-look solving, only 3-look solving (but you can pre-look OCLL-EPP)

Nice diagrams. I do not know if recognition is actually easy. The recognition with opposite colors for step 1 and step 3 reminds of trying to recognize 2x2 CLL which is definitely harder than for 4LLL. Maybe the lefty sexy is easier for you but it's pretty slow for me.

You dont need recognition opposite colors for step 3, it's exceptional step 2.1 - skip OLL (when after F2L you have skip OLL) and you need permute edge before CPLL (for skip OLL you can also use 2-look PLL - CP->EP, but for this alg is used EP-CP).

Regarding "my best 4LLL algs was 2-look LLEF+2-look L4C" ; moving to one-look LLEF is very easy, there's only 14 algorithms iirc. But one-look L4C is more troublesome, though it's possible to learn some of the simpler cycles of 3 corners algs, and make L4C a "1-look / 2-look" step.
I think you're right about the problem of developing this method into a 2-step process, as there would be a lot of algorithms in the second step, ( I estimated about 200 - 250, but I'm not an expert ... ) , and two-stepping it brings the alg count down considerably.
Edit: while I was scratching my head and frowning excessively working out alg-counts, I see someone has Ninja'd me with the correct answer. Hopefully the wrinkles in my brow will have faded by tomorrow morning.

1look LLEF very slow for recognition for me. First i developed my own recognition 1LLEF system, but i dont like it. Fork method much better for me. I can find colors after F2L when i orient L-Shape, Line or dot.

True, but lots of them are long and ugly, with difficult recognition. They're basically an extension of L4C, and you would be better off executing full LLEF ( few algs, mostly very short ) then L4C ( 80+ algs, some short 8/9 moves, some plain awkward ) . I believe the total movecount for LLEF -> L4C end up OK, about the same as OLL->PLL, but the last step recognition for L4C spoils it somewhat.
( using edge control when inserting the last 'F2L' pair seems like a good companion to the LLEF step, unlike the OLL step, where 'dot-case' avoidance is the most popular application . There's also LPELL, where the last pair is made, then inserted with an alg that solves last-layer edges. )
