So I bought a 5'0" sweet potato and surfed it for the first time tonight. I really bought it for my son thinking we could both surf it. I only caught one wave as I was really tired from surfing a couple hours earlier. I took off kind of late and the board performed amazing. Fast easy to turn, and went down the line no problem for my 6'3" frame at 185 lbs.
So there you go, probably could have been better if I got a 5'6" or 5'8".
