Sparky,
Popular topic and lots written about it, do a search.
Basically if your a competent surfer and riding a modern short surfboard then that board is fine.
Dedicated kite board as an order would have less volume, under 6' and a little extra glass, straps to if ya want'em.
As no one will have just one kite nor will you find just one board.
Buy lots of boards and lots of kites locally it's good for the economy!!!
My current do all board is a 5'10 fish with timber keels surfs great and for light wind days it's a blast.

Thanks for that,
I'll start doing a bit more research.
