I use Bamboo fitteds and Magicall AIOs. I picked bamboo as it is more absorbent and DS1 was a heavy wetter. The down side is it takes longer to dry, but I had enough nappies to deal with that. Nowadays I mostly only use the AIOs (with a booster) as it is just DS2 in nappies and he's not a very heavy wetter (and DH much prefers the AIOs). The magicalls (I have the older styles ones) are less absorbent but do the job for us, and dry in no time flat.
