Surfboard?- sutable size / shape for kiting

plenty of info on this at
www.benwilsonsurf.com/

I just got a 6' x 18.25" x 2.25" daLewy custom, made for kitesurfing.
its got 2 x 6oz glass on the deck rather than 2 x 4oz. rocker and fins tweaked slightly to suit kiting and straps added. still super light.
it has the fcs peanut system for extra strength holding the fins.

Loco4olas is onto it with some good advise.

I couldn't help myself though and bought a new board.
At 1.78 & 90 kg I have had several strapless sessions now on my new 6'2" 18 3/4, 2 1/2 squash tail Firewire (including some decent size swell at Lancelin on Wednesday) and am totally loving it.
My strapped board is also 6'2" but is 18 1/4 2 1/4 swallow tail Pat Rawson epoxy.

That doesn't sound like much difference in dimensions but they feel completely different the PR is quite a bit narrower and sharper in the tail and would probably handle steeper, faster waves better but is definetly bouncier and doesn't feel or turn nearly as good as the Firewire especially off the top.
