Creating 2 Bounty hunter teams

With Mando and Greef farmable, one thing that's been in the back of my mind is what two BH teams might be useful in GAC/TW. So, which methodology do people see as the better idea? Make two BH teams for roughly equal viability or make the best one you can then make the best you can with the leftovers. Either way, what teams did you make. For the sake of this thread, lets say you have to make 2 teams primarily out of the bounty hunters.
