I think bris kites sells griffin. I would also demo the griffin trx 17m if I was you. It is much more nimble than the argo, so in the 17m size especially would be a much more enjoyable kite to fly.

At 85 ks you won't be doing much at 9 knots unless you are on a vector or Alaia. At 12 knots you will be powered up enough for a riding waves. The trx is very nimble, surprisingly so for it's size. Drop it in the surf in 10 knots and you won't get it back up however. Flies very differently to the Argo, but its is easy to get used to. Great low wind kite that loves to turn on it's wingtip.
