I am much heavier at 260lbs. My first board this past July was a Fanatic 11'6" and had 231 liters of volume. My buddy was begging to buy the board so I sold it to him and bought an 11' Fnatic Fly with 213 liters of volume. The 11 ft. board glides and turns much better.
My point go with less volume especially at your weight. From what I have read the reviews on the Naish 11'6" are great. At your weight I would drop to the 11'4" at a max. If you plan to surf consider a Mana or a Fanatic Allwave.
