Note that in that case the second block:

I am pleased with my F2B. Any tips on a more efficient EO/L6E? I feel like I understand the efficient use of M/M', but I don't understand the efficient use of U/U'. I pretty much always use U.

Don't place both UL and UR to the top with the last M'! It's very rare that it leads to a shorter solution - usually on the contrary!

I would use:

U2 M U2 M U
E2 M' E2 M'

E2 M' E2 M' (or E2 M E2 M) seems hard at first, but with practice it could be extremely fast. For example: https://www.youtube.com/watch?v=0pDUYRrGEy4

Thanks. I try to avoid E2 but it happens sometimes. In this case I didnt even see I can make the way you've done. Once again, thanks a lot. Nice trick.

Try to make something with you second pair during solving first pair adding some moves and looking for optimal solution. For example:
x2 y2
B U2 L' F D L2 D2 (7)

I've added 3 moves to solve the next pair as first.

That is absolutely incredible. I cannot imagine coming up a solution that efficient on my own.

 

[h2f]

I am not best Roux solver. My averages are around 28 sec. Doing the first block just play around with cube adding moves with layer where other sticekers of your FB are. In this case I've tried random moves. When I did B I've noticed a corner easily can make line and the edge is a part of second line. The other moves were the moves you did. For the beginner its a good strategy make it as you did - square and the second pair, so your solution is ok. And your second block is only 13 moves which a decent solve.

A very interesting solution with non-matching blocks and UF/UB instead of UL/UR.
Not my usual colors, but this FB seemed the shortest:

y x'
S' R f2 M F // (5)
U2 r2 U' R' U r' U R' U' M' U R2 // non matching blocks (12)
l F U F' U' l' // regular CMLL (usually I would do U' F R U R' U', but this leads to a cancellation) (6-1)
U M' U2 M // pre-EO for better UF/UB (4)
U' M' U' M U // EO + UF/UB (5)
u2 M' u2 // M-perm (3)
U R' // undo UF/UB to UL/UR and solve speudo-blocks (2)

It's a good solve. I couldn't find a trivially shorter alternative for your steps.

One tiny little note: the last part of your LSE starts as this (after the EO):
U M U2 M
Here, you place UR/UL to the DF/DB positions. Instead, I would use this:
U M' U2 M
Because M' is usually a bit quicker. Moreover, I use such fingertricks for the M layer that alternating M moves (M'-M-M'-M-M' and so on) are really fast and nice: use left (or right) ring finger to push BD to DF (M'), then push DB to BU (M), and so on.

So, for the last 11 moves, I would use:
U M' U2 M U' M2 U M U2 M' U2

Not shorter, but more M' instead of M.

Awesome. Thank you. My M slice finger tricks are not so good. It is interesting to hear about how other people do them.
