Looks like it has a big advantage to being able to keep the PWC running native and be able to rapidly change out for hydroflight. At times, it would be nice to have back my SeaDoo braking, and reverse and trim..., I would be eager to see how it works in the real world before dropping $4000.

I currently use my 300 Seadoo in my Sealver RIB, with hydroflight, and it can be tricky to maneuver that size of boat without reverse,and the boat would plane better with trim adjustment.
