Perch,
I don't know if your aware of Kansas City Paddlers located in Peculiar, MO, but it'd be a good idea for you to go there and try a few kayaks. They can let you try some out and help you define which one you need.
Once you've got yourself waterbound I highly recommend you go to Watkin's Mill and get fishing. Dpenrod will likely agree. We met up there a couple of times last season and it was the best fishing I've found for some time. Maybe we'll see you there.
Jesus still hangs out with fishermen.
