regardless of whatever you offer her, the question of feel is most important. she could have long arms, or short ones, or she wants the lightest and smallest setup, or she could want the prettiest gun, regardless of what it is. there is no one gun, one setup one anything that is the best. how many years has this question been brandy'd about? if its a Cyborg RX, Droid, Geo, Ego, Victory, Marw whatever. you can put the best of whatever in her hands, but if she is uncomfortable with it, it doesn't mean squat.
sorry, i don't follow "The Whiteboard" anymore. i have my reasons, but one is the fanboy, or the total devotion to it, as the end all. so its nothing against you or your writting/drawing, its more of the sycophants that i don't care for. so if this is something of the plotline, as you are looking for something specific for the story, then i'm not the one to look at.
