Thought about inflatables, but seemed like a lot of work to pump up, deflate and the wipe down all the folds.
Went with 2 Wilderness system Pungo's
We think separate Kayaks are more fun than tandems, but individual choice on that.
One tidbit, don't go with a 9 or 10 footer. Go with at least a 12 ft, tracks much better that a 10ft, and don't max out the weight rating, get one rated 50% ish more, than your weight. Will ride and track much better.
Very easy to haul in a PU, with a hitch expender. Boondox, makes a great one
