I don't know what your bankroll is but I went out with these guys last year ou of Destin FL and they were 1st class. http://www.backdown2.com/ Only did a 8 hr snapper trip with them but was talking to the mate and he was telling me how they specialize in 2 and 3 day Yellowfin trips. I was looking at their photo album on the way back to shore and they had one picture after another of absolute monster tuna. Super nice guys and they put us on a ton of fish.
