... do you think you'll ever put boots on the board, if so I reckon get the bigger one.
My son has the 141 with boots and he says its the best board ever. He used to ride a 132 and found no real difference in top end, as in the bigger board didn't feel bigger and since the board has great grip can hold tons of power. The 141 has better bottom end compared to the smaller boards and could handle rough water waaaay better than his previous 132 board, so the bigger board has a broader performance range. The so called stiff flex gives it great pop and is good upwind too with its added length and seeing as its mostly carbon, its light as, even the bigger one is easy to throw around.
Hope this helps,
Robbie
