I'm lucky to have a premium bamboo supplier of all types close by.
That is lucky. Does he have a website?
Badger: That's too bad about Frank Supply. That's been a great go-to place over the years.
willie: I think the thing to do is just search for bamboo poles, or bamboo slats. I have bought from at least 3 guys besides Frank Supply. Everybody seems to have about the same stuff for moso poles or slats, plus some other stuff. It's just a question of shipping and getting good quality, not moldy, not chipped up.
I just looked and two names I remembered from 10 years ago don't exist anymore.
Tam Vong is the other species of almost solid, but smaller diameter bamboo, along with Tre Gai.
