Rob & Brennan: Boring
Chris & Alex: More Boring
Derek & Drew: Boring
Reichen & Chip: Boring Assholes
David & Jeff: Boring
BJ & Tyler: Considered to be Assholes
Eric & Jeremy: Boring
Tyler & James: Boring
Don't forget Shola/Doyin, Andre/Damon and The Cho Bores. Eric/Jeremy were the only alphas with personalities they've ever been able to cast, though Chris/Alex and Derek/Drew at least had a decent storyline (which Reichen/Chimp, David/Jeff, Tyler/James etc. lacked)

They've still cast way more young stud teams than older guy teams - they've still yet to cast a proper team of two grumpy old men, so they should take priority over more bohunks.
