These are the AIOs we have used, although they don't quite seem your "type",
Kushies AIO (Newborn) - they worked okay for the very beginning, for outings, but I didn't realize my son had outgrown them, and we kept using them past the weight/size limit, hence a lot of leaking.
Bumkins AIO (Medium) - these were our favourites the first year, and we were able to use them for about 9 months. Very simple and durable, no leaks, but towards the last few months, we did use a doubler (tri-folded washcloth) if we were in a situation where we might not be able to change him straight away.
Proraps AIO (Large) - very absorbent, gussets that are great for leak prevention. My son outgrew the rise before the weight limit though, and the Aplix closure wore out a bit - if I had known, I would have gotten the ones with the snap closure.
Rumpsters AIO (Medium and Large) - the rise is low and they are narrow through the crotch, but they work fine for us. The ones with Aplix closures seem wider than the ones with snap closures; the snap closures have a better fit on my slim son.
Blue Penguin Re-Uz'm Elite AIO (Large) - we have the ones with snap closure. They are very absorbent, but the rise is too high for my son, so the fit is a bit strange.
Mother-Ease AIO (Large) - these are my current favourites; they are basically a white ME Airflow cover with a thick terry lining. Since they have side snaps, they work perfectly as pull-ups (which comes in handy for EC). If I could do things over, I would stick to Bumkins for the first year, like we did, and then use these as our only AIOs once the medium Bumkins were outgrown. We have way too many diapers, but I'm tempted to get a few more of these for baby #2 anyway.
My son was never a heavy wetter at night, and has actually usually been dry at night for a very long time, but of the ones I have, I felt safest using the Prorap and Blue Penguin AIOs at night, just because they are the thickest.
