My 6'4" Coil Flashback Fish, goes in most conditions and is nearly indestructible so if I could only have one board, i'd want it to be able to last as long as possible, my 8'1" McTavish is another great option as it goes in most conditions too, but it's not at damage resistant as the Coil.
6'8" Tyler Hairpin: Eggy shape that can handle pretty much anything. Paddles well, carves nicely, duckable and as an added bonus, it fits inside my car.
If fitness an issue, maybe a HPLB.
A mid 7' HP egg with a pulled in pintail, and assuming that we could have any fins, 5 fin. Big slot for single fin, and then thruster for normal waves and quad when it got hollow.
