I don't have an EVOD; because of the vapes I like I mostly use glass. The airiness isn't the biggest problem I've had. You may have read my posts about not being able to keep it warm enough to perform consistently. That has turned out to be a major issue for me (although other people may not experience it). I had to open up the air holes again, because with the liquid not vaporizing, I'm getting liquid in my mouth when the draw is tighter. I much prefer my carto tanks.
When I read your post about not being able to vape well in the cold I got my opportunity here in Florida to step outside and try it out at 58 F, you're absolutely right, it doesn't do well in cold weather, its vapor drops to less than half. Then I thought, 'what the heck am I doing outside in the cold?' and came back inside.
Other than that, with a solid week of vaping, (and my Husband has one too), we are really enjoying the fuller vape of the ProTank. We have MT3's and eVods too, ProTank has taken the lead as our favorite. We are running 30/70 pg/vg and rinsing the atty at every third fill. We are using Kanger 3.7 Batteries and the eGo Twist at 4 and the eGo others on Variable Voltage to get the best vape. We like to hear a crackle or two now and then to let us know we are doing a clean burn.
No issues, no dry hits, no gurgling, no mess. We are used to Kanger products and know how to maintain them to get the best bang for the buck. If I was running lighter, (more PG the VG), eLiquids, I would add another wick to prevent flooding perhaps if it started gurgling.
Some people are trying to use eVod atty's in the place of ProTank, since they are very similar and more available, we don't recommend that, nor do we recommend restricting the airflow in various ways. Either you love an airy draw or you don't but I saw a pic of a Gal who used a Boo Kitty band aide around the base that was sorta neat.
We plan on building our own atty's in the future using Face Meat's great thread.
Being realistic about what a Kanger Clearomizer experience is like, (MT3's, eVods), and properly maintaining the ProTank will lead to great satisfaction.
