Love them both. Use the hip 70's logo (4) on shirts, I'll take 10 in multi colors. Use logo five on hats. Number 3 is the best for starting out. You can always change up later. More than one is not a crime.
Like 5 the best, still not 100% sold on the design.... font's not doing much for me. I agree with most so far that maybe more than one "official" logo may be the way to go, could make the brand have a broader appeal. The Keep it simple rule also come into play here. 3 may be your best choice, but in something other than basic black and white
