I know this is posting WAY late - and doing so mostly for folks that come through, rather than a direct response...
I just bought my Jackson Coosa HD from Wildcat Creek Outfitters and demoed the Coosa HD and Big Rig. They had a fairly nice assortment of kayaks available. I believe the carry in-store, most of the Jackson fishing line, FeelFree, and the Native Propel's.
Also there is Rusted Moon Outfitters in Indianapolis (Broadripple) that will setup demos as well. Though, they typically have far less options available in terms of fishing kayaks. Last time I was there (last year) they had a Wilderness Systems Ride 115, and that was pretty much it.
