Approx.How many liters of foam are there in a Surftech Stretch Fletcher model with the dimensions of 6'1" x 19.13 x 2.5. I weigh about 155 lbs. I bought the board used and, although i ultimately would have preferred a smaller size, is this board way to big for me, or, is it possibly a good size for bigger waves?
