How do you do the F'? I can't find a fast way of doing it.
Left index (pull UFL to LFD). It takes practice to adopt that F' but I have found that it is really worth it for 2x2.

It's not the smoothest of algs for me, but the low movecount makes up for it.

I've tried, but I just can't get the last three moves to be good at all. Please could you try something posting like this for that alg?

Personally I do the F' R with one motion of my right thumb (after doing the U with a left-index push).
Sameer's word is probably more useful than mine, but there's an alternative

I hope I do this right...

R' F U' R2 U F' R
rf 7C 4R rd. 7Q 4D rf // original(I think) rf 7C 4R rd, 7Q, 7M rf

I've experimented with loads of ways to do this (inc. yours): R2' instead of R2, a plethora of different fingertricks for the F', different starting positions, OH pushes etc. I have found that my current version is the best for me.

Thanks! That's so much easier to understand. It's definitely faster than whatever I was doing before, but it still isn't great; R2 U R2 U' R2 U R2 U' R2 is faster for me.

Why don't more people use R2 U R2 U' R2 U R2 U' R2 for PBL? I think it's way nicer than the other alg.

Personally I prefer R U' R' U' R' F2 U' R U R. But I use yours also, it just depends on the angle.

Such a nice alg!

So pretty smexy F2L alg I generated. I'm too lazy to see if it's well known.

It is. The inverse is pretty good too.

Confirmed. Well known.

For sure. The preservation of EO makes it way better than the 11 move 2gen alg I've been using for years. I need to explore alternate F2L algs more. :/

I didn't know it. Really useful for ZZ, thanks.

Also, a PLL scramble from qqTimer that's actually quite good: R2 F2 U' F2 D R2 D' R2 U R2 (does the same as R' U L' U2 R U' R' U2 R L).

I haven't seen this written anywhere, but I've got a 3x3 PLL sequence that I use for "F" ... can anyone tell me if I'm just using something someone else already uses? I looked on the WIKI here, and I didn't see it. Also, it says that the "Optimal Moves" is 14 ... but this sequence is only 13. I would have added this to the WIKI, but for me there is no "edit" option.

B2 L U L' B2 R D' r U2 M' U2 D R2

Edit:
I've also been told that the M' counts as two since the centers are assumed as fixed. However, I also have an "r" in there which counters this and everything ends up back to where it started. Any thoughts?

It is important to note that in HTM a slice move actually counts as two turns, since the centers are assumed to be fixed.
Your alg has an M' which counts as 2 moves in htm. The above quote is from the wiki description of half-turn metric.

edit: also your post isn't a new method/substep so this is the wrong thread. I'd recommend the Random discussion one.

I thank you for directing me to the right place. Still trying to find my way around I further thank you for clearing up the M' = 2 moves. I hadn't thought of that because it is done with a single finger-flick (center turns 1/4 turn)... but I can see your point... it is the same as an R L' combo.
