Evolution:
My two main Evo. couples are Rogue/Garabit and Kitty/Lance.
I can also do Rogue/Pietro as long as Remy never shows up or is mentioned. One glance and I'm back to my Romy ways. Also enjoy the guilty pleasure of Rogue/Pyro.
Movie:
Rogue/Pyro, and the inevitable Rogue/Garabit that will happen. Because it must. Storm/Nightcrawler, they're sweet too.
Never read the comics, but I've done some history readings on the characters, so I'm not as lost during discussions. Rogue/Garabit, Psylocke/ArcAngel, Kitty/Pete.
Note about the Rogue thing: I think if they brought Garabit in, we'd see a different side of her. Assuming they cast and write him correctly, we may see something missing from the first two films. He'd bring her out of her shell, with the flirting and such. And lord knows Rogue has a thing for the bad boys in the movies. And Remy's the ultimate bad-boy.
