I am 5'10" 165 and have had several FW dating back to my first three Quadraflexes. At one point I had five different boards but now five years later I have settled on these: 5'2" Sweet Potato for the really small weak days 1-3 ft. (a really fat mushy three feet), 5'10" Hellfire for the bigger punchier 2-3foot, and a 6'1" Flexfire Direct Drive for everything else.
I do admit though, I have ordered and am waiting to get a 5'6" Potatonator, and a 5'11" Hellrazor to possibly take the place of or compliment the sweet potato and Hellfire. I will never sell or get rid of my Direct Drive and god forbid if it ever breaks I will immediately buy another one with the same dimensions. I have ridden this board in double and approaching triple Overhead waves in Cost Rica and Hurricane swells in Florida and it has never let me down and fills me up with confidence when the waves are consequential. Please do add this to your quiver!
