I keep mine buzzed to about 1/2" or so in length and it's great.
Also: Neatly trimmed goatee - check. Neatly trimmed sideburns - check.
I'm a pretty good sized guy too (6'1", 38" waist, 54" chest) and, well, as someone said before, if you wear dark clothes (and some cool shades) you're a Bond villain from the future.
