I realized not too long ago that on many 3x3 shape mods CLL/ELL would be easier to recognize than OLL/PLL, and that this might be true also even for their 3-look breakdowns ie. CO/CP/E vs. any bracketing of EO/CO/CP/EP.
Existing CLL algs dont generally present much issue for this method, but ELL for regular 3x3 are usually not center-preserving, and can also involve many M moves which are difficult on shape mods. I have simplistically attempted to compute center-safe ELL algs with cubeexplorer, but the resulting algs arent exactly execution viable.
A possible compromise i considered is to only orient 3 E-slice centers during f2l, use LL algs that may rotate the last center (presumably R), then finally 1 alg to fix U and R centers. I am however not sure at all how much difference a constraint of 1 center would make on LL (cubexplorer surely didnt find that much better ones), plus i have been unable to find even good algs to rotate said last center pair.
