I think I will make my wicks 4mm, but I have a bunch of 2mm that would otherwise go unused so I will double it and try it out. It depends on who you buy you wick from, I guess, it can be very differently made according to manufacturer. Glad you enjoyed the video, as I learn I like to pass it on and have made a great many new friends through this medium!
Great job on the Video VaporLady. I've been vaping T3's for several months and just got a ProTank today. Dang it's good. It will be EASY to build thes. I do my rebuilds alot like yours but using the pin INSIDE is a great idea, lol. I've been doing 1.5mm wick inside the wick and 1.5mm outsaide as a " Blanket" as you called it, lol. Cracked me up but it's so true, lol.
