I rode a '56 2006 Custom for 2 seasons, 1 year East Coast ice and 1 in the North Cascades pow. Great board for park jumps, the nose and tail are significantly thinner than most, equalling low swing weight. I was dissapointed in the "Infinite Ride" technology, it pretty near completely lost its flex on season 2. It handled surprisingly well as a pow board when mounted set back 2" or so, great for tight trees, little drops, not so much open bowls as it's noodly at speed. Fun to spin around.
It gets a 5 as a brand new board, but very short lived durability, (seems to fall apart as soon as the warrenty ends.)
