Welcome to our forum.
Also, if you search and find complaints about the water getting funky behind the jetpaks, these are all older tubs. They redesigned the packs in 2013 to make them much better, plug in at the bottom, easier to swap out and the old ones still had plumbing behind them, the new ones use a manifold design that's much cleaner.
The argument that you can get maximum power in every seat is not a good one. It may appear that you are getting maximum power, but that's only because the JetPaks are restricting the flow. With a properly designed diverter valve you can take power from an entire pump and focus it on one seat, rather than waste power in unused seats.
There was a company that used VSP's in their tubs? Who was that?
