With this one I like to bring it up to the U layer with a R/F move and apply an edge flipping alg to flip unorientated U face edges (i.e. (M'U')*4(MU')*4 or (M'U'M'U'M' U2 MU'MU'M U2) and leave a nicer OLL (sometimes even force an OLL skip.) It may come in useful when all the corners are orientated, but it's not always fastest.
Maybe I wasn't clear enough.
Basically you do the trigger three times to form a pair, and then all you have to do is reinsert the pair because the pair is in the wrong spot.

So, I asked this on the one-answer-thread (here), and got great answers already. But that's not a great place for follow-up. So, here's a thread dedicated to it.
I was looking for a better F2L edge flip algorithm than this: (R U' R') d (R' U2 R) U2' (R' U R). Based on the responses, it seems that this is the most efficient/common, and is the first listed on the wiki (#38): (R' F R F') R' U2 R2 U R2' U R
Optimal Algorithms (9 HTM):
F2 U2 R' F2 R U2 F U' F
F' U F' U2 R' F2 R U2 F2
R U' R U2 F R2 F' U2 R2
R2 U2 F R2 F' U2 R' U R'
RrU Algorithms (10 HTM):
R U' r' R' U2 R2 U R2 U r
r' U' R2 U' R2 U2 r R U R'
RFU Algorithms (9 HTM):
F2 U2 R' F2 R U2 F U' F
F' U F' U2 R' F2 R U2 F2
R U' R U2 F R2 F' U2 R2
R2 U2 F R2 F' U2 R' U R'
I'm having a really tough time figuring out a rhythm/finger placement, etc. for (R' F R F') R' U2 R2 U R2' U R. I looked on Youtube for videos on this algorithm, but haven't found any. Anyone have good suggestions on technique/finger-tricks? Or a video?
