I can't say that I have, but I do have a Hario mesh filter
for my siphon brewer that was intended for using teas (also yields a very french-press-like coffee extraction, allowing more oil through than the cloth filter... as well as silt). The mesh filter assembly also comes with a bunch of paper filters so you can get a (vaguely) drip-like brew.
I'm really taken with siphon brewing as a method.... so robust and open-ended. You can really change your method to suit your tastes easily with it.
My Christmas plans include the Baratza Vario, my TCA-3, a half-pound of Intelligentsia Kenya Thiriku, and this
new toy I just got as an early Christmas gift of sorts. Of course, my grandmother is a tea drinker, so that opportunity will probably arise. Any pointers? I'm guessing it's pretty straightforward, though I am curious which filter you're using.
