Out of the wake line-up the Reflex is gonna be the best behind the kite. Due to a flat hybrid 3-stage rocker. Flat between the feet and rocker in the tips. So this will allow you to plane and go up wind much better when you under powered. Although the Riders have been stoked on the Response and Recoil behind the kite. But you need to be powered up to get the most out of it or staying up wind will be a bitch due to all the rocker.
But the Flex in the boards are super sick and ride very well. Hitting kickers and rails have never been more fun with a board that really does what its suppose to do.
