I will add that the Lemo is better, at least so far, than the Orchid v2 or 3 or whatever it is that just arrived. The airflow is adjustable on the Lemo, even if it is a pain to adjust. I like having the option. Flavor wise, I'd say the Lemo and Orchid are on par. However, the Lemo is much easier to build. Personally, I think the flavor is better with the Russian 91, but not by a lot. The Lemo is a great value at around $30.
