Hi Bulabuck, I think you will find that the micronized that I offer is the finest grind on the market, other than instant kava. The problem is when you start to get the particle size to a small enough point, it will catch fire with most grinders just from the friction, the one that I use is made to address this issue so I can get the particle size smaller.
For a good traditional grind you might try the Papa'ele ele pu'u pu'u I still have some and it is going fast, it is on my website. Let me know if you have any questions, aloha.
