I use a bunch of Royal's. Emperor 6A is sweet, Crockett is a beast, Thunderbolt, Archer, Trebuchet, Griffin, Stinger royal is sweet. Thug, Battlemaster, Crab, Phoenix Hawk, Shadow Hawk, Osprey.
I have used most of the Royal's in my current unit at one time or another. Still have a bunch of them too.
Stalker is one of my favorites.
