I don't stick to the recommended inserts as using microfibre with DS means I'd be changing nappies every hour, he is a pee machine. So I just mix and match and I've never had any trouble . I like the peapods bamboo insert as it's fairly absorbent but can be folded to fit whatever nappy I'm trying to put it into. If you want to stick with the HH inserts then I found their hemp inserts with a microfibre booster was a good absorbent option.
