Does it matter?
Considering the "ratio", yes....it does. 
Lets just hope that if you do bring any 501st guys that I don't 'know' them already....

And as far as SW guys go, just don't try to impress me w/ some old trivia or whatnot that any reasonable SW fan would know... that's all I ask... but, of course, enough drinks in me, I might not care too much...
