Are you shooting for slogans, graphics, styles or something different? Is this for kinda a one off event style shirt or an always available 'official' club shirt?
For events or one off fun shirts, stuff like the Top Gun logo but renamed to something witty like Tap Gun or such would be fun.
For an official club shirt (for HB club fund raising, etc) the work shirt idea is nice. That or something in a polo or something that is nice, yet can be brewed in.
My personal preference is to keep extraneous stuff off of shirts. Something simple (maybe just a small decal on the front with the name of the club and logo) sure beats the sponsor splattered backs like you see on most event T-shirts.
