Charisma & Etiquette, Negotiation in SR3, Beyond a -2 TN Modifier Options

[LordHaHa]

Hey, need some advice from you guys. I have a few characters in my campaign that have high Charisma values (one of them is particularly high, as she has Cultured Tailored Pheremones 2). I've seen the applications to Initimidation and Interrogation, and Charisma's value to an Awakened characher is apparent in astral space or for summoning.

However, aside from negating Racism and probably giving a -2 TN modifer (Friendly attitude), Charisma doesn't seem to do much mechanically with these skills. Which is frustrating, because these are some of the skills my group use the most.

So, does anyone have any thoughts on how I can factor this attribute into these skills a bit more? I'm thinking of either SR4-izing the rolls for these tests and having them roll CHA + Skill (which doesn't appeal to me as that screws up the SR3 mechanic and it could add a shitload of dice to keep track of, not to mention screwing any low CHA character that doesn't have mad Social Skills) or making a Charisma/Social Pool to all Social Skill tests (which also gives me problems because I have to define the source values for the pool, keep track of it outside of NSRCG and it doesn't solve the problem because some of the high CHA characters don't have high Social Skill values and therefore couldn't make real use of the pool). I could do target number adjustment, but that's more micromanaging.

Any thoughts on the matter that could arrive at an ideal solution would be appriciated.
