Anybody help? Just learning COLL algs from PapaSmurf’s docs, and found the First here tricky. Can anybody explain how to execute this alg preferably without regripping, or smoothly, as in as much detail as possible?
R U R’ U F’ R U2 R’ U2 R’ F R
PS if you think it’s a bad alg, let me know if you have a replacement.
 
The way I do this case, is hold the headlights on right, then do L’ U R U’ L U’ R’ U’ R U’ R’
I personally find it better than that one.
 
That's what I would do:

Basically just do F' with left index finger and the rest should be easy, maybe those fingertricks are a bit hard to get used to and not that reliable.
Whenever I do the F’ from that position, it turns the S layer with it too. I might just learn the new alg, easier to execute.

R wrist. U push with left index from LUB. R' wrist. U with right index. F' with right thumb. R wrist. U2 left double flick. R' wrist. U2 left double flick. R' wrist. F right index. R wrist.
I hope that makes sense, and it's definitely faster than the RUL.
 
Ok I’ve decided to use my original alg, and I think I‘ve got it now. So I do R U R’ U, then my right index holds the S layer at UL, while the left index pushes and does the First. Then it flows easily.
I just use right thumb for F' and the rest is normal
let me know if you have a replacement.

You could try some Petrus FMC to get better and more efficient at blockbuilding/F2L. EO is also something that you should work on. Many people, like me, do EO very inefficiently. Also for COLLs use this doc:
And for ZBLLs(when you get there): https://docs.google.com/spreadsheets/d/1QGJKEyivpm1axo19eDokgItxqQC5pI2-YciVTezJ7JY/htmlview
Or:
Note that you can use the ZBLL sheet to look for alternate algs for COLL cases, that are better for you.

Yeah, I do slow solving quite a lot. I’ll try some full out FMC one time. Thanks for the algs! How would people do EO ‘efficiently’, by the way?

TL;DR: Use all of these- F R' F', B' R B, S R' S', S' U' S,

Hey! I'm not too experienced with Petrus, I just decided to do some solves with it today, and I'm anywhere from 20 to 35 seconds. It's really fun, I'm going to keep doing Petrus speedsolves! Anyway, during the solves I tried to do everything as efficiently as I could, my 2x2x2 blocks are sometimes only 5 or 6 moves, but I noticed that my EO stage was pretty inefficient, requiring upwards of 10 moves. Now, I had a goal in mind to figure out how to improve the EO step. It's inefficient because I realized I was only using one sequence to solve EO, F R' F'. Now this is good and all, it flips the UF and DR edges, but I was doing setup moves.....
Eh this story is getting too long I'll just give you the algs already xD
F R' F' flips two, UF and DR. - B R B' flips two, UR and UB.
S R' S flips four, UL, FR, UR, BR. - S' U' S flips four, DR, UF, UR, UB.

Petrus pros, what do you use?

Edit:
Making a list of all EO algs for Petrus. Includes Pyjam's algs and anything else I find right now:
F R'* F'
B' R* B
S R'* S'
S' U'* S
D' r U* r' D
r U' r' U2 r U r'
F' U* F
Fw R* Fw'
*= turn can be clockwise or anticlockwise.

Other good algs for EO:

Woah, thanks for the algs! I only ever knew of the ones including L/R and U, as well as the M move ones. Wait, I just realised, those are the ones I use, just done with the block on the left :).
Never used the wide move ones before though.

Is it not better to always solve EO with the block in the back? <R, U L> is a lot faster than <F, B, R>.
 
Ok so I’m going to move on to finishing F2L this week, and learn the last of the H COLLs. After that, if F2L turns out OK, I might review my blockbuilding in Steps 1&2, and also focus on inspection usage. I should probably learn how to do COLl recognition from at least two angles as well.

Quick question, is it worth having the ability to choose an easy 2x2x1 from 4 of the different options when finishing F2L? Or should I just use the 2 on the R layer?
