The graft is like the artifacts big brother as Nivek mentioned. Its very soft in my opinion. The Jibpan while it has "jib" in its name is more of a high end park board that handles all mountain freestyle. I found its a better jump/pipe board than a straight jib board. For 150 snag it up and know you'll be on a killer board.
WWW is a limp dick Jibpan is more like soft serving a girl after a bit too much drinking, its hard, its soft, its inbetween.
