The person you REALLY want input from is Mark Sher of Inland. He was the one that came up with the idea of the bag that Fly High sells. Just for the record, Fly High can make a custom sac to fit any dimensions. They made one for my Tige
I'll give you my 2 cents.
The custom sac is a rectangular sac that fills up the rear locker with an extension or finger that fills up every square inch under the bench seat. I am doubtful you have the same available "real estate" on the drivers side. You'd end up having to balance the ballast to get a decent wakeboarding wake that wasn't mushy on one side. Plus...that would be a ton of ballast, close to 2500 pounds if you filled both sides. Did you need that much for wakboarding?
Because of the way the sac's are designed, if they aren't filled, the water does slosh. Even when filled there is some sloshing, but it's not really noticeable. Once the boat reaches a constant speed, the water stabalizes in the sac. When there is room in the sac, because it's not filled all the way, that sloshing is very pronounced.
I am not a big fan of the wakezup/switchblade for wakesurfing. It's functional, really makes a big wake, but I have found in the three instances I've been behind an Enzo with the switchblade deployed it threw up a spray close to the boat, making it hard for me to see - water in my eyes. Now, Marc (not Mark) has actually taked with Rick Lee the owner of Centurion and was assured that what I was describing was an isolated isntance - or maybe three of them
I would recommend demoing it before plunking down your money - they may have corrected that isolated instance(s)
, or it was in fact, just that. I've never wakeboarded behind the Enzo so can't speak to the use of the switchblade for that purpose.
Too much weight? Sure just ask your patrol next time you're out.
For wakesurfing, there is a balance. Too much weight in th rear of the boat creates a very steep wake and no amount of height makes trying to ride a vertical wave fun.
The Enzo, when weighted appropriately, is probably one of the best surf wakes out there.
