During my build, I put two drops of unflavored directly on the wick and used a couple of drops on the liner to make it easier to wrap. I filled the tank, let it sit for...oh, maybe ten minutes? Looked for leaks. Took some unpowered draws with the air-control closed, despite the useless of this step with the M.

Started taking two puffs at 6 w and two puffs each up in .5 increments until I was at 11 on the iStick 20. I was going to push how high I could go, when I got distracted by Nanny's question.
The stock coil got a drop of the flavored e-liquid down the chimney and one on each airhole, sit, repeat the puff procedure.
And the stock coil is still improving. That's the one I'm vaping on right now. I should probably have waited until about now to do the test. The rebuild is still on the vv3 and I don't want to play the tank shuffle, but I still give the rebuild a lead. But that could be from the rayon. Glad I did this. Why did I wait so long? It wasn't hard at all.
