Jackson Kayak's soon to be release Coosa model should be on anyone's short list for kayak fishing, especially fly fishing since it offers one the ability to stand-up. Really it is the first kayak designed for fishing rivers. All other fishing kayaks have been designed for fishing lakes or ocean waters.
For list of features and a couple short videos on the Coosa:
(I hope posting link is okay, if not mod feel free to remove)
Also I am early on the waiting list, once it goes into production (late Oct). If anybody wants to test ride, I would be more than willing to let you play around with mine.
EDIT to add:
Jackson Kayak is a TN company, I always like supporting local companies whenever possible.
