If you are looking for comfort and stability, try out the Pro Angler series from Hobie. They do cost more but they are exceptionally comfortable and stable. And the Mirage drive won't cause any pain in the shoulders or back. The disadvantage is it's weight out of the water, it is heavier than most kayaks. However, the loading and unloading is not as bad as it might seem, and you aren't doing that all day. You might be able to find a place to store it at a location near the launch. I don't know if there are any openings but Dana Point Jet Ski offers storage there, and they are right on the water. Not sure if OEX offers anything like that but there may be other places that do.

I have a PA and love it, I usually stay on the water from the time I launch to sunset, the seat is very comfortable and the drive system is low impact on any joints and muscles. I have a knee that acts up occasionally but the kayak does not aggravate it.
