I want to buy a new surfboard. I am 6'5" and weigh roughly 165 lbs.?

I have been surfing for about three years on a 9 ft. longboard in charleston. I have tried a 5' 6" shortboard and know damn well that that aint happening. I was thinking about a retro fish since theres so much mush here in folly beach sc. just any advice would help me tremendously.
