I've heard that the classic style is slowly going extinct, due to regulatory issues that make getting the proper wood for smoking within the traditional growing region difficult. Jin Jun Mei ensures that the tea-growers will do well, but some folks think it competes with Lapsang for the same bushes.
My personal favorite, Hu-Kwa, might not count, as it is a Taiwanese lapsang copy that developed during the U.S./China trade embargo to replace true Lapsang, and that remained in Taiwan after the embargo lifted.
I am also a fairly minor Lapsang enthusiast, as if I drink too much smoked tea I tend to feel a little queasy. I am not a smoker of other things, which probably reduces my smoke-tolerances.

Does anyone have any favorites? How do you brew it?
