gzacckey,
I float many of the waters you mention. I rented a watermaster once on the upper Del and had a great time. Since then I've bought a Bucks Bags pontoon boat, which is my craft of choice for floating. With a pontoon you are higher out of the water, quicker to maneuver, and have better back support. Yes, it may be a bit harder to store, but it's worth it. If you have to, you can disassemble and reassemble. Shoot me a pm if you want to float sometime, you can never have too many float buddies. There are lots of great floating opportunities in that area.
