tooling cost for curved boards are considerably higher than for straight ones.
And you can debate the pro's and Cons for ever, but the only ones I see arguing that the curved boards are not a definite performance gain are those that have not even sailed a relative boat with curved boards... I suggest you all go and try them before passing judgement on the performance gains and the ease of use.
I'm with you on both points; I see them as an advantage.
