Hi, guys! I'm learning roux now. My average with it ~ 1.30. Could you give me some tips how to search for edges on a cube more faster? It's the main problem for me to find correct edges on the cube =/

Well this question is not exclusive to Roux, but more about blockbuilding in general; I am just posting it here because Roux is the first new method that I want to learn.
I am a fairly competent speedcuber who uses CFOP, but this means that learning blockbuilding based methods is extremely difficult, because I end up just slotting like in F2L. Even FreeFOP is hard for me. I recently read AvGalen's Fewest Moves thread because I wanted to try and do Fewest Moves, but blockbuilding the F2L turned up to be unexpectedly hard. So I typed "blockbuilding tutorial" into the search bar, but nothing much came up.
I also want to learn ZZ and Petrus in the future, so I will definitely need to learn how to blockbuild properly. Are there any tutorials for blockbuilding? I will try and see if I can find anything in tutorials for specific methods involving blockbuilding.
EDIT: found DeeDubb's Roux tutorial. Gonna watch it later

try consciously identifying exactly which piece your currently looking for. then when your searching around the cube for it, softly whisper the colours to yourself. so if you looking for the red-greed edge, just whisper that over and over like a crazy person untill you find it. that may help you in the beginning.
well block building is basically glorified slotting (unless i misuse the word 'slotting'). the most common procedure for building them blocks, at least for me, is doing something like this:
(so i originally wrote out a bunch of detailed stuff, but thats confusing so i'll just give you the short of it. speak up if it is too simplified)
1) make a center edge pair (like an unsolved crosspiece)
2) create a corner-edge pair elsewhere on the cube with out disturbing the other pair (the colours should be used in accordance to the colous making up your center-edge pair)
3) connect this corner-edge pair to the center-edge pair
4) bridge two centers with an edge piece, (like a solved cross piece) (which centers you bridge are dependent on your square colours)
5) using an R, R2, R', or a move like that, connect the square to those bridged centers. you now have a 2x2x2 block.
6) without disturbing that block (let's say it's in BDL) use Rs, Us, and Fs to do the same thing as you did in steps 1-3, but this time the two centers are already bridged so use colours that will eventually connect with it. you now have a petrus block.
7) now the cube is more retricted, so it is more mechanical and can be visualized more easily by a cfop user... i think.
kso, its hard as heck to describe this in text and im not a good enough writer to be able to clarify the block-building process through this medium in any reasonable amount of time. so ask question if this sucks too hard to understand.
Oh, cool, so I'm doing something right. (the whispering like a crazy person)

Okay, thank you, I'll try

Just filmed some OH solves! Im getting into it (and other events 
) a bit more. Anyone have any advice? (...other than "practise" and "learn to turn")

try not table abusing while doing cmll, it's faster to rotate in air. i'm not a fan of too much table abuse in second block, primarily because i use right hand, so use you sub 10 lookahead to get set up better last pair cases.

i think half my rotations are unintentional cube drops. good of you to see how cmll is one of my weaker steps. so for second block should i just not use M moves? lol now i notice the pauses but i dont wanna switch. also, is there a way to actually see what is happening while doing LSE table abuse (on FR edge)?

pretend the back is the front, when you need look and the front , or just do RD edge.

nope. thas way too hard. ok i guess that works, yeah.

Maybe get a smaller cube? I use a 50mm Zhanchi and it's great!

I dont buy cubes often (only have 4, and my parents are sort of skeptical about me cubing too much) so I probably wont be able to get a mini 3x3. isnt 50mm a little small? my hands are pretty big anyway so 57mm cubes arent that bad, but I would probably go with a 55m weilong.

Meh I have 5 + clock but I can't solve 4x4 or clock and two have been borrowed for about as long as I've had them

OMG this sounds exactly like my parents! They are like "why do you need more than one cube"...

Setup 1 : M'U2 M U2 M U2 M' U2 M2
Setup 2 : M'U2 M U2 M2
Any good way to recognize these cases, and any better algs to solve the cases other than the inverse of above? Especially for the first one
And, good EO algs for -
1) Wrong edge on DF, and other wrong edge in U layer
2) Wrong edge on DB, and other wrong edge in U layer
Setup 2 : M'U2 M U2 M2

Don't have any better algs for those EP cases other than what's been suggested already for case 1, and the inverse of the setup for case 2.
2) M' U' M' U' M U' M' (or swap U's with Us)
1) flip DF+UB: M' U' M U' M' U' M' (or swap U's with Us)
2) M' U' M' U' M U' M' (or swap U's with Us)

1) M U2 M' U2 M2 or M' u2 M u2.
2) M2 U2 M' U2 M or u2 M u2 M'.
Recognition: keep tracking of the BU or the DB sticker (or peek if you can't track).
Also for a 3-cycle on the M layer note the perfectly fitting edge (DF in the first case, UF in the second case) and the completely-not-fitting edge (DB in the first case, DF in the second case).
(completely-not-fitting = none of the stickers are matching with the centers)
a) Make an M / M' / M2 move such that the perfectly fitting edge is on the bottom, the completely-not-fitting edge is on the top: M (first case) M2 (second case).
b) U2
c) M' if those edges were on the back after step a). M if those edges were on the front after step a).
d) U2
e) Finish the cube with the corresponding M / M' / M2 move.
Mines are:
1) DF+UB = M' U M U' M' U* M*
2) DB+UF = M' U M' U M U* M*
Where U* can be U or U' and M* can be M or M', depends on the UL/UR edges.
