What is the best way to solve green orange pair in the back right slot from here?

I am now finding that I tend to just do a R’URU’R’URU2 to just set it up asap, otherwise it seems to be one of those rotate first, set it up then rotate again to insert cases...

I'd just rotate twice, actually. You can also try something like (U) Fw R Fw' to set up the pair then U' R' U R to insert; this is equivalent to B U B' but executed differently.

I'm working on an intuitive big cube method, and recently realized that it shares many techniques with Roux. For 4x4, I like to force the last 5 corners into an even-parity 3-cycle while solving the last edge of the second block. I heard that Alex Lau used this technique in his Roux solves, but I can't find any specifics about it. Does anyone have any information about this? Thanks.

I'd solve the orange-blue pair first, because I don't know efficient solutions for most misslotted-F2L cases. I'd probably use one of the following two solutions:

(ii) R2 U2 R' U2 R2 to insert orange-blue, then U2 F' U' F for orange-green. (This happens to be the optimal solution for solving both slots.)
(i) D R' U2 R D' to insert orange-blue, then y' U' R' U R U' R' U R for orange-green.

Thanks. I like that one with D moves, that’s what I don’t know enough of. I really need to start incorporating them into my solves. Still averaging 16.5, not going to stop until I get it down to 13.5...
