Speaking of Empire mods, Daniele, I saw this: Dream Stainless Steel Rebuildable Atomizer and thought of your Phoenician airy-draw woes. It wouldn't hold as many drops, but it's got an adjustable draw, which is really cool!
I saw that Dream rba yesterday morning on their site but didn't read the details. That does sound sweet.
On the phoenix there is a poor man's trick for a tighter draw... just place a small piece of scotch tape over the air hole, then with a needle or pin, punch a smaller hole inside the stock one. Might be worth a try.
