I use West Systems. One squirt from jar A one from jar B. Can't beat it.

I got my carbon through Aircraft Spruce and I don't remember where I bought my hemp fiber--I just searched for "hemp fiber" and picked one.

The bamboo I bought was already dried, I'm sorry but I don't know if the smoking process did anything but change the color a bit and made the wood smell good.
When I bought my wood I bought two different verities of bamboo, Black and Moso.
Some of the black bamboo split during the smoking process. The rest has been stable for several years now.
I did not smoke the Moso and it split (with sudden and loud pops) over the next two years just sitting in my shop.
Of the 80 feet of Moso I originally purchased, I have maybe 12 feet of usable wood. I won't buy moso again.
