We started out with bumgenius pockets and once DD outpeed the microfibre, i added a bamboo booster to the microfibre, when she outpeed those we used an easypeasy hemp. So maybe try bamboo first?
Only tried zorb in our night nappies (littlegumnut) and had one charcoal insert and didnt see much difference from bamboo or hemp really

So would be interested in other peoples opinions of them too.
