Mine's the S22, so we share a hull and engine, but yours adds internal ballast. If you're lucky and have the wet floor, you'll have a nice 800 pounds or so of well-balanced weight on top of what I'll show you...
I use the sacks below just because they're big and were really cheap - you could get fancier and get some custom sacks made for cheap that'll fill your spaces better. Anyhoo, I don't use the sac covers and fill them about as much as they'll take. One goes sideways in the trunk, and one goes all the way forward in the walkway. Together you're talking 1400-1500 pounds. It really makes a big difference behind the boat, but while speed control is a little tougher, the boat still planes and handles very well. A wet floor ballast would add nicely to this! Also, I always carry between 100 and 200 pounds all the way forward in the bow just for trim.
If you're more willing to lose your v-drive locker storage for the day than the trunk, you could get a pair of custom bags made for there. I may end up doing this someday because you can get 1300 pounds balanced back there under the engine hatch and it's a little farther forward than the trunk (and I do use the trunk for board storage). I would probably make a bulkhead for the port side so that the space matches the size of the starboard side - right now, the port side extends all the way forward under the seats.
The Bump leaves a bit of room in the trunk on each end and in height too, so if the 700 back there isn't enough for you, you could have a custom sack made for it too. If you went longer only, you could probably get up to 800 or so, while a rectangular sack of greater height could really get you well over 1000. If you were to do that, you might need to look at the strength of the removeable bulkheads there - don't want to push the bulkhead into the engine's drivebelt, etc. You could reinforce it or replace it with a stiffer material than the composite board used. If you really filled the trunk, you'd have to add a lot of weight to the bow (maybe lead under the seats in addition to a walkway sac). Ideally, I'd recommend equal weight between trunk and bow, whereas the v-drive lockers you could maybe go 60% in back, 40% up front.
For the most part, the wake is fun empty but with a few adults. I've been enjoying it with just a single Bump in the center of the cockpit (the aft end up against the tranny cover), so that would be pretty comparable to you running with just the wet floor ballast.
