I'm actually in favor of the long goatee with the chinstrap. And here's why I say that: you seem to carry more confidence in the pictures with the long goatee than with the short goatee. I think confidence is the biggest statement any fella can make with his chin art. And I will second what Dano said, the first picture looks the best. While I like the longer goatee, I wouldn't go any longer than in that first picture unless you plan on letting it all grow out from there.

The mustache is not a question. Grow it.
