I'm not sure how the flex on the Capita is
Naner is pretty noodly, but supposedly has been slightly stiffened up this season.
Capita is regular camber with flaired up edges to keep the control outside of your feet
Naner is rever camber which keeps the control between your feet and makes it feel more like a skateboard
I think the Capita is an all around better board. But if your a skateboarder, you will likely side with the naner. I'm a big guy and have a narrow stance, I want the control area to feel large and help with balance.
Plus Capita is a much smaller company and is much more deserving of someones purchase in my personal opinion.
