I'm 6'3" 205 lbs & I highly recommend Jimmy Lewis 11' or 11'6" Cruise Control

I took a SUP class on Maui last fall and the instructor hooked me up with a 11'. Me and my family have rented several boards by other manufacturers, but the Jimmy Lewis is by far the easiest board to ride & has the best construction. We also longboard and found the Cruise Control to be very surfable in smaller waves if that's what you want to do. The quality of construction is the best I've seen. The deck pads are integrated and cushy. The board is also very light for its size- my 105lb wife can carry it. The price is very competitive with other boards but the quality is far better.
