You've been pushed around long enough! With the Nerd Rage! perk, your Strength is raised to 10 and you gain 50% to damage resistance whenever your Health drops to 20% or below.

I could see if he was desperate in a life or death situation, but having a trait for biting someone to death? Dude is an expert sniper, stealthy, mystic, and I really do not see him biting another man to death.

Biff is, uhh, cheap.

Flo gets a discount at Tonys. That is worth her cost almost immediately if you do a lot of business with him.

Flo costs $255 a day and gets a 10% discount at Tony.

This means you have to deal in weapons with Tony for $2,550 every day to at least be on +/-0. And this goes up when Flo starts to level. You can only achieve that when you completly ignore ALT+LMB and ship each and every gun you find down to San Mona. This in return requires someone like Hamous and his truck to be occupied with not much else than driving weapons to San Mona. And all this to return you the salery of a merc that otherwise is useless?

You just can't sell Biff. You either get him forced on you when everyone else is dead or you make a mistake and hire the wrong guy.
He's actually pretty cheap for bullet proof vest standards. And he's mobile!

Tank distraction? Probably cheaper than a smoke grenade.

On standard settings he gets equipment earlier than Bobby Ray does and is a better source of rare ammo.

I often leave Flo camped in Tony's back room the entire game. And I never, ever peak in on them without knocking.

uh, that's a bit more in information than I wanted to have....

? I've never seen Gumpy replaced in the last One-Click installers. What do you mean???

I always have a whole squad that's only doing logistics

Razor?
Virtually needs no sleep. Knifing expert. Good physical stats.

Haywire?
Razor's buddy. Knifing and auto weapons.

Hamous?
Stealthy. Okay physical stats.

Shank?
Well if you train his strength and dexterity he can be a grenadier.
