I discovered this algorithm for Fridrich's "Y" permutation a while ago, and am curious if anyone uses it besides me.
Here it is: FLF'R'F'RF'L'U'FUF'U'F2

Are you seriously executing it like that? How long does it take you?

I guess you mean: x ULU'R'U' RU' r 'U' y' RUR'U'R2

Erik's is definately better. My Y perm is smooth, but I can't seem to get it sub 3.

(F R U' R' U' R U R' F') (R U R' U' R' F R F')

The parenthesis are just to make it easier to read, they don't denote any specific finger tricks.

Err speedy it is exactly the same alg as posted only in a more fingertrick friendly way...

Huh? He didn't even say he does. Personally, I prefer very clean notation without any fancy tricks like (l U') x (R' U2 R) [(r' U' r B) (R' U)] or (R' U2 R' d') x (l' U R' U') (l R U'). When I see some really messy notation like the examples, I have to first remove all the needless things and find the core alg. Then I see if I like it or not and how I would perform it.

About the Y-perm, I use the inverse and its mirror. It's really nice, especially for OH and one ZBLL-case.

Well he said he uses it. With no further clarification. To me that implies it's how he uses it. I don't like excessive amounts of execution annotation, either, but lots of F turns seem just unreal.

You see, Erik, I have a horrible time trying to make algs more friendly for my fingers, esp if I need X and Y turns.

I would like to use your alg, but I keep messing it up!! And today my mind is blank, I can't memorize things... I'll just save this for a later date.

Actually, I perform it this way: x ULU'R'U'RU'r' y U'LUL'U'r2.
I get it under 2.5 sec. consistently, and sometimes under 2.0 sec.

Sorry about the core form; that's how I would write them down.
I made most of my OLL and F2L algorithms a while back. I remember when I discovered how to make LL algorithms (from the solved state): "Break apart the F2L, and then put it back a different way." Then from there, I decided not to look at Fridrich's list of OLL's until I found all of them. Eventually though, I just HAD to peek at a certain one of them.

Looks similar to the inverse of Joel's
R2 U' R' U R U' z' y' L' U' R U' R' U' L U
which if I remember correctly he got from my
z' U2 L' U' L U L' y' L' U' R U' R' U' L U
which I got with ACube a while ago.

Joel I think uses it but I don't (yet?).

If I only had more time I would ...
