I don't have the Provari's but do have the Evod's and in my experience they are way too airy for me as well. I was shocked since I was told that the evod's were less airy than the protank mini, but I found the opposite.
I broke off toothpicks in two of the
three holes in the base of mine mine and it improved greatly.
Ultimately this was one of the main reasons I switched to the Mini Protank 2. It had a tighter draw and I preferred the "feel" of the trip tip better. The eVod's mouthpiece was too big for me.
Try getting a couple of Mini Protank 2's. I think they taste better and they are easy to completely disassemble to clean. Not that the Evod's are hard to clean, but they take a while to dry. I can completely clean and dry a Mini Protank 2 in less that
three minutes. And because they are made of glass, you can use them to sample anything you want
Sun Vapers has them on sale for 11.99 each which is just .02 more than they are at
fasttech. And you know they are authentic at Sun-Vapers, and you'll get them in just a couple days instead of a couple weeks. Plus Sun Vapers has replacement glass in stock so you have some spare glass in case you get a case of the "dropsies".
