My experience. Four seasons rolling. I wanted a capsize recovery that was quick and flawless.
I could'nt learn in any of my folders I had at the time. Folbot Aleut or FC Kahuna.
Once I learned "the kayak roll" (DVD title of technique I learned) in a Prijon Seayak, I could roll both the
folders, but I had to set up with an exaggerated hooking of the knees under the decks,
they were not recoverys, merely tricks. Both the folders actually recovered very well to
primary stability once the hip snap motion was grooved in.
I got thigh brace bars for the Kahuna and I considered the roll a recovery after that. I did'nt have to
adjust my knees prior to the capsize. The Kahuna was (I sold it to my cous) a good roller.
The khats fit tight right away and I had a roll dialed in. I have been on and off hand rolling it, but I quit
paddling it for rolling games, and switched to more anthrodimensional SOF's.
This spring I built this, does not fold

, which is comparative volume and dimensions to the Khats , it rolls well
and I hand roll it at will. I'm still developing greenland style rolls, it's fun, but I'd rather paddle.
Here is cold water rolling and bracing on May 1st this year, with the SOF # 3 I have built.
