^yes. My smoking technique is pretty much the same as yours. I drag straight to my lungs at first (2-3 seconds) until the back of my throat tingles and I'm about to cough. Then I take the rest of the hit (5-7 seconds total drag time) into my mouth and then suck it all into my lungs with a big gulp of air. I hold it as long as I can 20-40 seconds and then let out the hit. In almost all trials I exhale no visible vapors or almost none; I've actually wondered if I was getting vapors in this whits, so I just pulled into my mouth and let out--it was a nice cloud.

So correct me if I'm wrong--you are using approximately 3ml of ejuice to 1g of spice. So that would be a 1/6 ratio.

So many unknowns... We should set up a conference in Denver, all meet there for the weekend and I bet we would have this thing nailed down in a weekend.

As for me, I'm spending today researching ecig basics so that I understand their function a bit better. Have a friend coming into town tonight who will try the pen and will report back accordingly.
