I rode a 08 superjet for a few years and now on a carbon ROK. I loved how my superjet railed turns, it was super easy to hang off the side and drag yourself in the water. Yeah the ROK is a little more difficult than my SJ to get it to lay into the turn and when im there I feel like im going to lose it and fall to the water so I compensate with steering. However my ride time on it is short, so I may just be trying to ride it like my superjet. Once you get the nose down, high speed stability is as good as my old superjet, but it does like to ride on the left or right chines so it's a bit to get used to.
