I just got my protank 2 and the first 2 attys through it were fine. I ordered some thorough myvaporstore and none of them seem to have good airflow. It's so tight that I can't get any air through. I don't really want to loosen it as it starts to feel wobbly.

I notice a different rubber grommet on the new ones right at the base of the atty by the battery connection. White on the originals ones and more clear on the new.

I am not very impressed so far with the PT2.
 
Overtightening tends to compress the older white insulators, blocking airflow. I've done some tinkering, and fixed mine so it works great.

1) i drilled the three airholes in the base out one size, 1/16" i think. tiniest drill bit you have.
2) ream the center of the base with a 5/16" bit. Just enough to remove the burs from the first step.
3) Place your coil head in a pair of vice grips and LIGHTLY compress down the length. The insulator may "smoosh" out a bit. use a nail clipper to trim off the material to be flush with the head while compressed.
4) reassemble and test. Should work MUCH better.

Finally, if this has loosened it up too much, use a $4 airflow controller to fine tune your draw. i have found that the draw does tend to tighten up with extended use of a coil, gunk building up on the flavor wicks and coil I think.
 
So, like, wow. I bought an additional Protank II, with the new clear insulators.

I don't like them. They are VERY soft, and compress too easily, blocking airflow even more than the white ones. I did my usual trick to trim the insulator, but still have to fiddle with the threading to get a reasonable draw.

Good thing i have a good supply of the white ones to rebuild with...
 
Yes I just bought mine today along with an evod and the evod which is known to have a tight draw is very loose and enjoyable. While my protank 2 is SUPER tight I just tossed the flavor wick in the atty and it helped a little but not significant it's still a little tight for my taste. Try removing that flavor wick you really don't need it anyways unless your using high PG based e-juice like a 80% pg juice
