PT2s have slots in the base to let air in and the Provari doesn't block them. If anything, the draw from the Protank is TOO airy.
Using a Loki beauty ring can somewhat cover part of the holes but not enough to stop the airflow.
I really don't know what those other people are talking about when they can't get a draw
through a PT2.
Mine have always been airy as well, but I have read too many posts lately by people who have had a problem with the draw being too tight to answer with
Well it didn't happen to me, so it can't have happened to you. That kind of garbage runs rampant on the forum.
Inadvertently, I was one of the first 400 people in the US to get a Protank, so I have witnessed all of the issues that have come up - from the glue being messed up on the first run to the bases snapping off. Since the too tight of a draw issue is something recent, I have a strong feeling it has to do with the update of the bases more than the devices being used. As stated in the Sweet-Vapes product listing I linked to:
"2 versions to choose from:
Version 1 is the original base on all older V1 ProTanks. This has about 50% larger air holes.
Version 2 is the base that comes standard on all V2 ProTanks, and possibly newer V1 ProTanks. This has about 50% smaller air holes.
The only difference is the airholes, if you prefer a tighter draw, choose version 2. If you were happy with the airy draw on older protanks, choose version 1."
It's quite possible that on some devices the newer bases don't get enough airflow, it happens. I just discovered tonight that the new Aspire BDC Vivi has no airflow with the Bobo.
I don't have a fix for the draw being too tight, but I do have one for the draw being too airy, so I have no issues with the draw on mine. I still think the flavor is muted, but I only use the Protank for unflavored, so it doesn't matter.
