    Default 4x4x4 OP/DP algorithms (more finger-friendly)

    OLL Parity (RUL):
    Lw' U2 x Lw' U2 Lw' U2 Lw U2 Rw' U2 Lw U2 Lw' U2 Lw U2 Lw (25q, 17f)
    Lw' U2 Lw' U2 Lw U2 Lw' U2 Rw U2 Lw' U2 Lw U2 x' Lw U2 Lw (25q, 17f)
    Rw U2 x Rw U2 Rw U2 Rw' U2 Lw U2 Rw' U2 Rw U2 Rw' U2 Rw' (25q, 17f) (Yu Nakajima uses this, Lucas Garron found it)
    Rw U2 Rw U2 Rw' U2 Rw U2 Lw' U2 Rw U2 Rw' U2 x' Rw' U2 Rw' (25q, 17f)

    Double Parity (RUL):
    Lw U2 Lw U2 Rw' U2 Lw U2 Lw' U2 x U2 Lw2 U2 Lw U2 Lw' (25q, 16f)
    Lw2 U2 x' U2 Lw U2 Lw' U2 Rw U2 Lw' U2 Lw' U2 Lw U2 Lw' (25q, 16f)
    Lw' U2 Lw U2 Lw2 U2 x U2 Lw' U2 Lw U2 Rw' U2 Lw U2 Lw (25q, 16f)
    Lw' U2 Lw U2 Lw' U2 Lw' U2 Rw U2 Lw' U2 Lw U2 x' U2 Lw2 (25q, 16f) (mine, I switched )
    Rw U2 Rw' U2 Rw U2 Rw U2 Lw' U2 Rw U2 Rw' U2 x' U2 Rw2 (25q, 16f)
    Rw U2 Rw' U2 Rw2 U2 x U2 Rw U2 Rw' U2 Lw U2 Rw' U2 Rw' (25q, 16f)
    Rw2 U2 x' U2 Rw' U2 Rw U2 Lw' U2 Rw U2 Rw U2 Rw' U2 Rw (25q, 16f)
    Rw' U2 Rw' U2 Lw U2 Rw' U2 Rw U2 x U2 Rw2 U2 Rw' U2 Rw (25q, 16f)

    Just for comparison, here's the "standard" OP alg:
    Rw2 B2 U2 Lw U2 Rw' U2 Rw U2 F2 Rw F2 Lw' B2 Rw2 (25q, 15f)
    See how much it sucks?

    I can also post FRUL and FRU algs in case anyone's interested, but they're not as nice as the RUL ones imo. I think Yu Nakajima's alg is the best, here's why: no double turns (all Rw and Lw moves are quarter turns), and it alternates between Rw/Lw and U2 moves (i.e. quarter turn, U2, quarter turn, U2, etc.), which makes execution non-stop and super smooth. But I just like my alg better for some unknown reason

    In case you didn't know, you can always use DP algs to fix OP. It doesn't really matter because it doesn't increase or decrease your chances of getting PP (still 0.5).

    Edit: There, changed.

    Thanks for those. I really like Yu's OP alg.

    wow..I thought everyone uses the same algo..how naive of me..Yu's looks good I'm definitely trying it..

    If the current one is not as finger-trick friendly I wonder why most people use it?

    Btw blah, all the algs posted are basically for OP right since you can't predict a PLL parity anyway

    Man... that alg is NOT Yu's.

    Lucas came up with that alg a while ago, and I've been using it for at least 10 months. Nakaji probably just found it from a few sources, one maybe being http://www.youtube.com/watch?v=84eud2DR2-s

    Erik uses the standard one. I tried to get him to convert, but he didn't.

    What times can you people get with your algs that you're using? I can get 4-4.5 secs (probably slow) with Frederick Badie's algs for OP and DP.

    I never use the double parity alg, but I get sub4 pretty frequently with lucas's OLL parity.

    I use the double parity alg, but I rarely need to. I only use it when I can easily spot that I have a double parity.

    Um... what you do is you solve it and keep one edge flipped. If you find out at the end of OLL (with one edge flipped) that you have PLL parity, do a double parity alg. If you don't, then just use a normal OLL parity alg. Then you have to do a maximum of one algorithm.
