Chubby thighs here, and we get that problem of the snaps pressing into DS's legs. Same with the OSFM Happy Heiny pockets, but even more wing droop with them. Haven't had it with the Blueberrys though, and it's a bit wider. Strange.
Although they're fantastic nappies, I would shop around a bit. I bought heaps of BumGs early on, and now I want to change to something different but can't afford to without selling some off first.
