I agree with the tan (or "pebble") shirt working the best. I tried the other colors as well, and it provides the best contrast while still being "tactical".

That new logo looks friggin' sweet! The back looks perfect, but since we have all the club info on the back now, we need something better on the front. How about a subdued "Don't Tread On Me" flag with snake, or the hilarious ubiquitous sandbox "fun meter"

Or someone who is REALLY artistic needs to design the club a shield/crest.
