I made several posts on this thread about my wicking problems with this tank. (Single coil user.)
I do TC builds and was getting partial dry hits which is totally bizarre for TC and should have been my first clue.
Problem:
I am wrong handed and wrong headed. I was wrapping and mounting the coil so that the lower leg was mounted to the negative post and partially obstructed that juice channel.
Solution:
Wrap the opposite direction so that the coil can be mounted so that the upper coil leg goes into to the negative post. No more channel restriction! I wicked it the same way I had tried a dozen times before and it is working through 3 tanks so far.
Should have posted a pic and it would the problem would have been obvious. I am posting this to maybe help someone else who is completely new to this type of build deck.
My apologies in that this tank is now tootle puffer approved in single coil mode and I may invite other tootle puffers to join the thread

(I like slow, hot, dense MTL so maybe not exactly a tootle puffer.)
This tank is great and worth the effort to figure it out for a slow person like me!
Thanks for the guidance.
