Just to be a bad ass mo fo against you're average person I'd pick wrestling hands down. Odds are, even if you are good at stand up, you're gonna find yourself tied up with someone. You can really make people look flat out stupid if you have even a remote wrestling background. You might be physically weaker, but you'll come out looking far stronger by just knowing positioning and body movement alone. I've watched a 103 pound state champion make a 245 pound defensive end look like a fool. It it truely glorious. A wrestler can generally make your average joe's face melt. You don't even need the submissions at that level. Ground and pound.
