I use the same cages and water bottles you're looking at, have been for several years now, and they work great. I have two with 1.3 breeders in them and one for my growouts. I use a lot of paper towels around here, the growouts love running through and chewing up the empty tubes.
Mine have always had huge litters, in 1.3 it's not uncommon for me to have 30-40 pinkies at a time. It's pretty wild watching them nurse too, the females will take turns just laying sprawled out on top of the mountain of babies.
