Yeah, looks good
I know I'm a little late to the party here, but I've found flipping the little rubber grommet on the chimney completely solves the burning issues I've had. The airflow seems to be a ton better too... I was about ready to give up on my protank ii when I saw this simple solution on reddit. Game changer.
I keep pet rats.
And I love going to Renaissance fairs in medieval garb.
Did a rinse,and dry burn, and flipped the gromet. Way better hits, no burt taste...for now.
I ordered some SS mesh. From what ive read it wicks faster than silica.
I believe that the burnt taste is from lack of juice begin wicked. Since the gromet covers part of the wick holes i feel like it prevents the juice from wicking well imho.
Either way, flipping the gromet works well to get more juice flow. Hopefully SS mesh works just as well or better.
If your putting out more watts, you are vaping juice faster, therefore need to flow juice in faster.
Id try flipping the grommet first if your using the 1.5 or the 1.8 ohm coils it should have good juice flow at 4.2 v. If you wanna go higher volt and lower resist(by rebuilding coil), id try the ss mesh for faster wicking.
