well i bought it on dvd and in europe so it cost me about 23 euros.
i didnt think the trick tip was that good, since it was very brief and general. it didnt help me alot personally. though i found it good that they featured young and newer riders.
unfortunately there was no double except for the first shot, if i recall correctly. and no i dont mean a dub cork, but a cool stylish double like a kang or dub back.
