The one we rode on during one of the summer demo's buy Supra rode great on the rough water. The tower is solid and did not wiggle one little bit.
Surf wake was very good. Dealership had changed the left rear bag to a 750, boat had the liquid lead option plus I put a 400 bag on the floor and another under the seat on the left side. We couldn't fill the bag under the seat full with my bag, but I think you could have a bag made to fit that space that weighed that much.
Nice wake - at first there was only 4 on the boat and then 9 later. Of course with 9 it was better!
