Pairings?

Okay I know this is meer of a 'Picks' section vraag but it's easier here. I'm writing a FanFic the main parings are Bridgeoff and duncney (sorry gwuncan fans) so what other pairings should I have? And I am have trouble deciding between gwody ans gwent (should I have the story start of with one of the gwen pairings an then a break up of have her decide between the two (trent and cody)boys)... please lijst any boy+girl pairings (I WILL put in a splash of noco for the fan girls though.)
