the striker is the element. its just the old name for it but its basically the same board, however, with the pilot seat. the twin tip jokers are probably better, however dave jennings could do all the same tricks on the old one as he made the board. kustoms are more of a slalom board, but can be used for tricks, however, it is a little more work. im not sure how the 720 is. i have a friend who uses it as a slalom board but i was told it is basically the original striker.
