Insert Help

Happily Overwhelmed

I've been CDing for 3 years now and it's time to replace a lot of my inserts for my pocket diapers. I have mainly microfiber and they are getting pretty thin. I've been considering swapping them out with bamboo as I like the antibacterial feature. My boys are heavy wetters so also really want something to hold as much as possible. I'm getting thrown off by my options though. I'm seeing a ton of bamboo with microfiber layers inside. These always have more layers---which I'm assuming would hold more. BUT wouldn't that cut from the antibacterialness? So should I go with 3 layers---bamboo only? 5 layers of bamboo and microfiber mix? Something else? What's your favorite insert?

ETA--I do own some hemp I rotate in depending on the need.
