Another green you can try is Gunpowder (note, though, that a black Gunpowder
is also available). One I like is SpecialTeas No. 531 Temple of Heaven
Gunpowder China. I find this tea to have a distinct flavor that I think has
subtle smoke, leather and flower components. Also, I find it's fairly
forgiving of time and temperature, and you can get at least two very good
infusions.

I've also tried the Gunpowder from Special Teas, and at first I didn't
like it, but it grew on me because it was flavorful and relatively easy
to brew.
