so, this year's C133 is fatser than ST137 in < 15kts?
Where did I say that, I just said it is a fast board, faster than many seem to think and from the number of carve 133s on my local water I have seen this first hand.
I have also seen less skilled sailors struggle to get a decent gybe from the ST but pull off good ones on the carve. It's just the nature of the board. In the hands of a skilled rider the ST137 is superb, I just feel it requires more input than the Carve.
