I think it'd be cool if you secretly pull a guys name out of a hat and a girls name out of a hat and have them be the troublemakers (so if you pull two exes that were already paired, draw again till it's a troublesome pairing :p). I think the randomness could be a great creative exercise for us, you know, having to adapt to something that might be somewhat unexpected.

But, that being said, I wouldn't mind casting votes either, if that's what the majority wants.
