Boosters go in the middle of your diaper and they usually swell up when wet, so it's going to be hard to avoid a waddle if you've gotten to the point of soaking your booster.
I've tried AwwSoCute diapers but they are NOT high sap or high capacity, the fit isn't that great, and they have no front/rear elastic. (so I don't like them at all) I don't suggest them for extended wear because they are low sap and odor will be a problem after awhile.
Safari are probably all you will need for daytime wear, I don't think you'll need a booster. But that being said, they're pretty wide and thick in the crotch already, you might already be having problems with a waddle. They're one of my favorite diapers for overnight however. I can wet a lot overnight but I never need to boost a Safari.
Northshore Supreme or Crinklz would be my recommendation. Crinklz have VERY tall (and far apart) leak guards, they're one of the best diapers to boost. But again it's going to get really thick between your legs if it gets very wet. Try without a booster first. Northshore is also selling limited-edition special art crinklz (aquanaut and astronaut) you might want to try.
