No I don't have them, but both are around for demo. Check with Matt Sexton, he can point you in the right direction on the Slingys.
Also, Danny is selling that Hyperlite wakesurfer for a great price, which looks like a very fun board to kite on.
My Zap fish is really undersized for kiting but you're welcome to take a spin on it anytime. It is incredibly fun!
What I love about about skimming is:
feeling overpowered and totally out of control in 15 knots( or 30!)
being able to ride in 4" of water- on low tide you will have EB or SW to yourself. I recommend gloves if you're in the shallows-I got a lot of hand cuts bracing my falls when learning.
The stoke of being a newbie all over again! You'll be shocked at how much you learn without fins or straps regarding kite control, body positioning, and going upwind.
Just be ready to leave the twinnie in the car and get lots of "dirty diapers" from crashing.
Check out Lose The Straps, there's a ton of good info over there.
