On a whim I just ordered a couple of Jade and Pearl sponges. I will let you know how they go if you are still curious. I think it was you that was asking about them?
They are natural, don't have any chemicals, create less waste (they are actually compostable once you are done w/ them), and like @Rrrrrachel said they dry you out less. And a much lower risk of TSS than disposable tampons. And I have heard they are way more comfortable than regular tampons.
