I really like the idea of Rodney/Teyla but I don't see many stories with them. I think for me I may have issues with Teyla/Sheppard because he's in command of the team and she's a woman (in the wrong hands it can easily look exploitive, i'm more sensitive when it comes to women in fan fiction), it's also one of the reasons I'd have to separate Weir/Sheppard from Atlantis for me to really believe in that pairing.

It also helps that I've read some good fics with Teyla/Rodney (example: The Silent Art of Watching)
