I am looking to buy a sweet potato however many of the surf shops around me aren't sure on how to size this board. I have been told to buy a 6'4 and as small as a 5'4. I am 5'10 weighing in at 185lbs. I am going to be surfing it in New Jersey and Virginia. I am planning to use this instead of my longboards. I don't have any short boards to gauge a size jump as I am long boarder. Can you guys give me a some feedback on this? I would really appreciate it.
