A tip for you: if you are having problems visualizing a way to solve EO, take one of the bad edges from d (if there are none, do an M2 to put one or two there), and then put one of the good edges on u directly above it, and then do a M/M' to bring that bad edge to u. You will have misoriebted the centers, but you will usually be a little closer to the arrow.
Thanks for the tip. I will definitely try it out and will also keep trying to understand the process. My first impression is that Roux is fun, after so much CFOPing lately, trying to push for 1 second improvement, and then for another... now I have lots of seconds to improve, hehehe. Well, seriously, it is fun and not only because of time beating.
