Let's see, I should probably quote my post from last night..sitting here again after getting home from work..just topped off my cart with coffee and going to town!
I actually decided at work tonight I'm gonna be a coffee nut with this thing. My next order, which I'll put in next week (after researching a bit here) will consist of a few basic coffee flavors (hoping that there's a good espresso out there somewhere) and then the likes of: vanilla, caramel, mocha, cinnamon, and cream (if there's something like this)..and making flavors from that which will rival your local starbucks..life is gonna be good.
Actually, smoke rings come out better if you don't inhale. Just keep the vapor in your mouth to puff them out.
I've found that inhaling all the way initially then letting large puffs out into your mouth at a time, and then making those each into several rings, is the best method. For me atleast.
If you know what circular breathing is, it's a technique expert musicians use to hold long single notes, it's something like that.
