Check Craigslist every day for "kayak". Try and get your hands on a Dagger Blackwater 10.5. I have both the older model and a newer model. Short boats behave like much longer boats if they have a "drop down skeg". The Blackwaters have skegs. With the skeg up, you can turn on a dime. When down, it will track like a 17' sea yak. I can't say for the boats you desire, but I think you'll enjoy the better tracking with a skeg boat.
