I agree with MarkSmith and can add some details about the ABU Super Dry Kids (SDK). ABU is currently selling the second revision (SDK V2) of is this diaper on their website. It has soft plastic that is very quiet and a pretty thick pad that holds a ridiculous amount. I normally don't go number one in my diapers, but when I do decide to I flood a huge amount and this is the only diaper other than a Dry 24/7 that has not leaked. I'm not really a fan of the V2, though, because I'm more into the feel and sound, and the plastic just isn't crinkly at all.
If you do a search on eBay for "ABUniverse SDK V1" you'll find that they are still selling the original SDK. I love this diaper (wish I could buy it with no printing, though) because it is SUPER crinkly. The pad is a bit thinner which is ok for me because I'm not a huge fan of bulk. But if you want to go number 1, beware, one of the major reasons for ABU going to the V2 is that the V1 didn't hold nearly as much as the V2, and before they would reach capacity they would leak right through the plastic backing because it would develop develop very small cracks. That doesn't bother me though, because all I ever do in them is go number three and then fall asleep!
