I've been using the Advance race dragster for one month and i am very happy because it is a very good bord for racing, the current leader of the Italian racing championship also use this board (maybe now he is second but, i am not update after the last race
All production boards comes equipped with fins a bit too small, also North and other commercial brands, because very long fins are hard to ride for the average kiter but Advance dragster comes equipped with a size of fins that is quite good for medium-strong winds (over 12 knots):
2 forefins of 26 cm. and 22 cm. the backones, this set-up is good for an average use, only if you are seriously intrested in racing and condition are mostly about 8-10 knots buy another couple of fins of 28 cm. to put ahead and move the 26 in the back position.
This board is easy to use but very fast upwind, it must be ride flat and let go fast not too much angle upwind.
Be sure that you'll have nothing less than a North or a Monaro... maybe something more
