Being new to Roux, I find it amazing how you can make your second block 15 moves or less in a speed solves despite tough cases like this.

most of the last pair cases are better than this one, and a few are just as or worse but are always fingertricky. 20 is a pretty good movecount for second block if you can do it. when you has most of the cases down efficiently and can lookahead better and thus influence the last part of second block while doing the first part, 15-16 doesn't seem to hard to believe. if you get any more hard cases, i'd be happy to give you my solutions.

In my first solution here, I found the second block really hard (okay, not hard but long). Any suggestions?

Hi, I have a question about CMLL. According to http://grrroux.free.fr/method/Step_3.html D3 is symmetrical to D2. However, after heavy searching, I can't find any D2 and D3 algorithms that are symmetrical. I've looked for example here:

If anyone can tell me which 2 algorithms are symmetrical I'd be grateful. It might mean 1 less alg for me to learn.

EDIT:
And the same for D5 being symmetrical to D4

EDIT:

D2 = R' F2 R' U' R F2 R' U R2
D3 = Sym(D2) = (U') L F2 L U L' F2 L U' L2
It's mirrored to the R/L plane.

D4 = R U' r' U' F' U F
D5 = Sym(D4) = (U') L' U l U F U' F'
This one too.

So basically if you pick up an algorithm, use its mirrored version for the other case (possibly you have to adjust it with an U move before).
However, sometimes the mirrored case is harder if your non-dominant hand is not so trained. I use different algorithms for different cases even if they are symmetrical. And this is why most of the algorithms you won't see mirrored versions: <R,U> is more comfortable than <L,U> for a right-hander.

Edit: for example, I use
D4 = U' F R' F' R U R U' R'
and
D5 = F' Rw U R' U' Rw' F R

They are not mirrored; but both of them using R, U and F moves, so it's more comfortable for me.

So, I've been practicing mostly CFOP but recently, thought of the idea of if I just solved my F2B however I want, without any restrictions. So like F2L, I solve two cross edges, and then an f2l pair (right or left) and then solve another, but it can be on either side. Is this good if it works for me better than the other way (FB, SB)?

EDIT: forgot to mention that I just got a 21.99 second Roux solve doing it that way.

what ever is faster, but in the long run, yours will be more moves and with rotations, but of course perhaps easier fingertricks like f2l.

Thank you Renslay. Though I'm right handed, I generally find L+R+U (like Niklas) combinations easier than F+R+U. I think I'll use Waffle's combinations for D2-D5, since they don't use F, but I'll try the ones you mentioned as well (I generally give all algs a try before settling on the one I find easiest).

zomg pbs are fun i wish i broke mine :(

thnx :)
I rly like roux and am starting to consider switching to it as a main method, though it's really tough to give up cfop when im this fast...even if I don't end up switching, I at least would like to be sub 20 with roux, one day. my biggest problem is lse eo. I totally understand eo and all, but it's hard to wrap my brain around how to do it. the way I do it right now is kind of "do whatever until I get arrow" which is not good bc it usually takes like a lot of moves. Ive looked into an algorithmic approach, but there aren't many resources for that, and the alex routorial on lse has like 3 cases which totally helps lol.
also, one day I want to be able to do the thing where you don't have to adjust the m slice before eo and can do it without that but that's advanced stuf lol
tl;dr eo help pls
