theres a little bit more to it than that>

like what:
...kind of board? directional/twin tip/skim board/surf board/lilo
...kind of kiting do you do? waves/flat/river rafting?
...kind of tricks?

i use a 6'1 surfboard for kiting in the surf, a nobile skim board for light winds and small waves and a 128x38(i think) wood core flx with soft-ish rails and heaps of flex.

Lots of flex helps you pop and land, but then again if you want to jump high in the sky a sharper edge is needed. well, that also depends a lot on your kite....

arggh, faaark i don't know.. anybody else got a clue?

yeah dont worry about it too much its just some general info i want on twin tips, i like agressive freestyle and newschool tricks. so any good frestyle board. what features should it include, how does the stiffness of the flex affect its pop and landings? does double concave do anything for landings? is it better to have a biger or smaller board for powered low flat tricks? whats better for boosting big etc. its not like im going to go buy a new board soon as i did 2day already but its just something usefull as i want to get some knowledge for the 1 day i open a shop
