Definitely get a Fijian strainer bag. I got mine from Paradise and it blows every other straining method I've used out of the water. Not only can it handle the finest grinds effortlessly, it is also basically indestructible. Usually a muslin bag would really only be good for about a kilo of hand squeezed kava before it got so clogged or just ripped, not to mention how frustrating and user unfriendly it was. The Fijian ones are really big and I never realized before how big is much better in addition they are super easy to clean and dry almost instantly. I have put several kilos of kava through my Fijian strainer from PK and it is still in perfect condition, no clogs or rips.
