I modified my Envoy ever so slightly.
I ordered three "spinner jets" and installed them. Now, I have two spinners in the corner seat directly diagonal from the filter compartment which make a huge difference over the two straight shooters that came in it. I also changed out the straight shooter jet in the seat between the two corner with another spinner so that seat now has three spinners.
When I sit in the corner diagonally across from the filter compartment, and turn the pump two air control toward the head of the lounger, that spinner hit the lower back and creates a fantastic massage.
