Have you called extreme kites? Since they are on the east coast, regularly surf waves, and are usually brutally honest about what they sell (if something sucks they may even refuse to sell it to you unless you beg and pleade), I would definately give them a call and ask to talk to the big D.

Honestly, I really don't think you are going to want to ride any form of surfboard in flat water, so don't bother with a psuedo surfboard because it might do a little of everything but it will do nothing very well.

If you really want the feeling of surfing, get a real surfboard or kite-surfboard (small, with staps if you want). Otherwise you are not really surfing... or at least not for more than a second or two as you briefly slide down the face on a high dollar skimboard.

No point in asking here since only a handful of riders here truly kite surf or even ride in the gulf regularly for that matter. Call someone on the east coast!
