The SA will certainly put out a wake comparable in size to the 24. Truthfully, with the right amount of weight the SA wake can get bigger and stay much cleaner due to the hull shape. Like TN22 i've ridden an SA with over 5000 pounds in it and the wake is scary huge and clean for miles.
To the OP: In my buddy's SA 450 we are running fly high 1100's in each of the rear compartments and stock flex ballast up front. The bags run all the way up to the very ends of the compartments, so if you don't mind losing storage space and want all your ballast hidden, this is probably the way to go. We have also found that running this amount of rear weight makes the wake a good bit steeper (which we like, both having upgraded from loaded down Supra 22v's). The 450 is able to pull this weight setup on plane without a problem, however, i'm not so sure the smaller motor would be able to handle such a rear heavy weight distribution. Doing the 750's in the rear compartments will certainly give you more kick as well, and fly high just started selling 750 pound sacks made specifically for the SA, so that's definitely something to look into. This is probably the route I will go, as we just ordered an SA and went with the 350 motor. Either way I'm sure you'll be able to create a wake you love as much or more than your 24! I was certainly skeptical about the SA because i loved the wake on our 22v so much, but after some time in the boat I can say that the wake is as much an upgrade as the awesome handling and styling
