I'm sad to say it, but I have been buying Kona Kava Farms powdered kava root for over a year. Didn't know any better, until last week when I discovered these forums. I had suspected KKF was not a good vendor, especially recently as their product has been weaker as of late. It has also been of variable consistency - one order of medium grind was practically micronized. I am running low on kava now, and so ordered some GHK M'oi and Papa Kea. I'll report back with a comparison. Trust me, if anyone can make the comparison it will be me, although I suspect you guys have heard it before.
