Horses for courses I guess, but I'm not sold on the banana shape for getting going on flat water with small or high aspect foils. If you're using swell to get going, then I guess it might help. In flat water flat rocker with a sharp release on the tail allows you to quickly get to a fast enough board speed that you can take off. Any rocker on the tail just feels draggy to me.
It's increased board length that flips the script.
Agree, I have a Carver. 20" x 6'2", flat tail
great interview with Ken A above. He actually acknowledges the compromise on planing, but points to other advantages the rocker brings
