- Basic:
    - Front arrow (setup: M U M)
    - Always ends with arrow (1/2 time doesn't work) (demo setup: M U M U2 M U M U M U M)
    - Watch bottom too: Recognize without looking at bottom (even number of flipped edges)
    - Back arrow (setup: M U M') avoid repeats, push from tip
- Intermediate:
    - 2 flipped
        - 2a x4 -> Arrow (as seen; note: none on bottom; reco) (setup: M U M U2 M U M [U*])
        - 0-2 -> Arrow (setup: M U M' U' M U M)
        - 2-0 x2 -> Arrow, same as align [otherwise repeats] and M2 to bottom but canceled (setup: M U M' U' M U M' [U*])
        - 1-1f x4 -> (setup: M U M' U M U M)
        - 1-1b x4 -> Rotate? Inverse. (setup: M U M U' M' U' M')
    - 4 flipped
        - Arrow x4 (already know)
        - 4-0 Swap UF/UD, arrow (setup: M U M U2 M' U2 M)
        - 2-2 x2 Cancel into M2 + 4-0 case (setup: M U M U2 M' U2 M')
    - 6 flip
        - 4-2 (M' U' M') -> 1-1 -> U2 (M U M) -> Arrow U (M' U' M') (setup: M U M U' M' U' M' U2 M U M)
- Finger tricks (M'/M2, M push, U'/U2, U back index)
- Advanced:
    - M/M' U* M*
        - Example: 1-1b Simpler (setup: M U M U M' U M)
        - 2a -> easier
        - 4-0 -> easier
        - Good EOLR Arror (setup: U M2 U' M U' M / U M2 U' M' U M / U M’ U' M)
        - Ensure 1-1 LR (setup: U M2 U' M' U2 M U' M' U M)
    - 6-flip: R U' r' U' M' U r U r' (setup: r U' r' U' M U r U R')
    - Algs for all
- Cases:
    - Arrow (front): M U M (AUF x4)
    - Arrow (back): M U M' (AUF x4)
    - 4-0: M U M U2 M U2 M
    - 2o-2: M' U M' U2 M U2 M (AUF x2)
    - 2a-2: M U M U M2 (AUF x4)
    - 2o-0: M U M U M' U' M (AUF x2)
    - 0-2: M U M' U M U' M
    - 2a-0: M' U M' U2 M' U' M' (AUF x4)
    - 1f-1: M U M' U M U M (AUF x4)
    - 1b-1: M U M U M' U M (AUF x4)
    - 6-flip: R U' r' U' M' U r U r'
