Heavens, no apology warranted. And even though Avid Vaper says the open post atomizers will work with bottom feeders, I'll probably still write to them and ask them to confirm the claim. I'd hate to go ahead and order a squonk mod (extravagantly and against my own resolve to be content with what I have--or soon will have, when the Sandstorm arrives) only to find I can't use it.
