Biovals are well biodegradable so they break down. If you get a drop of water on the BB it starts to break down and warps and becomes gummy. I have also heard of them leaving a lot of gunk in the inner barrel when you run a lot through your gun. They are suppose to be getting better. And yes most people either love or hate him. I personally will only run bios if I have to (a lot of field require you to use them).
