PT2 restricted air flow?

[stevegmu]

Original PT head is Airy
Original Evod is Tighter - Smaller center opening and thicker lower coil head for reduced air flow
New Protank/Evod head looks to be more to the PT style. Haven't gotten any to compare yet.

Not sure which ones my Protank 2s came with. I got them from ProVape. My replacements have Protank checked off on the back of the pack, so must be for the PT1. Maybe that's why they were so cheap...
