A few more thoughts... The seat is great; the best I have experienced, and due to upper curvature it even tolerates life vests that aren't super high-back. The kickup fin feature gives huge peace of mind. I would never bring my old fin drive to the shallows I experienced there, altho due to high tide I wasn't aware of any hits. I prefer the rugged simplicity of the included non-180 fin drive. I added lanyards to both drive and paddle (which did pop one end off a time or two).
The manual pump is great even with my sore back. If you use the 2 way feature early, the electric prefill seems not needed. Nice to have a pressure gauge, although hard to pick out the 2 target levels. Too early to tell if the folding up is gonna remain hard, since when new they are stiff and unmanageable anyway. I may prefer the old style bag which had built in 2 way cinch straps and could be rolled up and placed on the boat enclosing pump.
Probably due to the side bulbs I experienced the most secondary stability ever. So I can tilt and just hold it steady, to for instance perch level on a big broadside wave (seen in picture B below). I used it for turning fast also, mainly to avoid being tilted outward by centrifugal force. A crazy application may be to heel a sail into the wind like the world speed record boats (75mph) depicted below. Then I am counter weighting the wind force while remaining centered in the seat. Maybe get dumped in a lull tho:
