Ive decided to go with 42lb injectors and an 80mm maf for my 9 psi (powerdyne) supercharged cobra that i will be modding further in the future (heads, cam, intake) and i wanted to know what size throttle body i should go with. Ive read that 65mm is plenty for most setups and that bigger is not always better, but i just want to make sure. What do you guys think?

You read wrong. First of all, what intake manifold will you be using? If your stock now, just keep the stock TB and hold off until you do h/c/i. Then i'd run a 75mm tb with that car and if the manifold inlet isnt a 75mm opening, port match it w/ a dremel.

I'm gonna slowly sneak out the back door before the internet racers and magazine racers get a hold of me and beat me up

70mm TB at least and be sure the tb matches the inlet perfect.
