well i'm not sure about the nipple thing. i think they work with their own brand. i never used the drop-ins, because i just throw everything in the dishwasher. (i know you are supposed to boil, but my dishwasher has a "sanitize" mode so i figure it's all good!)
you didn't ask, but i recommend avent bottles! they are really nice.

i second the avent bottles! the whole system is great. the deal with the fast flow is just that there are more holes in the tip of the nipple. with avent i think the fastest has 4 holes. i always just put everything in the top rack of my dishwasher too.
