This is what the good ride had to say about the kink:
Intermediate to Expert Freestyle Jib
Flat Camber Twin Like Directional Shape
The Kink has a solid build that is made to deal with the jib park and not much outside of it. The Kink is pretty soft and playful. This is called low pro rocker but it's more flat camber than rocker. What ever that means it really means that the Kink is pretty stable between Jibs and is fun to play with.
So for some reason their borders that tested it thought it was twin-like directional but yeah, on the sportchek description it says it is a centered true twin.
Even so its still meant as a jib board and the Raygun will be better all mountain/on bigger jumps. And is over 100 dollars cheaper.
