Ronie is easy, heh, I keep her in a tin can, she should stay fresh for years.
Cass, I give her the 3 variations of Raider outfits, she swaps between them as and when she chooses.
ED-E, runs around naked O_O

Maybe I should implement my 'ED-E wears a hat" mod.
I usually keep Ronie on ranged attack using a revolver, it gives me time for a couple of a clear shots before she runs in, she's not too bad with a gun and it's great fun teasing her. And yes, she does have a hammer or fist for when things get up close and personal.
Cass gets the good guns, I'm usually EW so it saves me taking my life in my hands arguing with whiskey woman. She also has shades.
I leave ED-E with his menacing beep-beep attack or whatever it is he does, as if there was a choice
