jibpan is a much better board.
the graft is basically an artifact with some carbon and such, more comparable to the k2 darkstar.
The Jibpan is basically the www on steroids. Its got carbon stringers throughout giving it a lot of pop. Its got a sh!t ton of effective edge since its got that whole jib inspired thing k2 does (shorter nose and tail with more effective edge). with more effective edge, you get to ride a shorter board with the control of a longer board, it feels awesome. AND, the jibpan is tapered at the nose and tail making it easier to spin. and my buddy delamed his graft last year.
