2011 Malibu VLX weight/wedge setup suggestions

My buddy just bought a 2011 Malibu VLX. It has the four tank mls ballast and and the power wedge. We rode it for the first time yesterday. with stock ballast full we rode 65ft at 22.5 and 70ft at 23.4 with the wedge between all the way down and 3-4 clicks up. The wake was great. We're curious to see how other people are setting their boats up both with stock ballast and some extra weight. Between the normal guys that come out we have 2 400 lb bags and a 1000 lb triangle bow sac. How would be best to utilize all 3 of those bags? Naturally I'd want to say triangle in the front and the 400s in the lockers but every boat is different. Also if we wanted to fill only one of the 400 lb bags on top of stock ballast where is the best place to put it?
