my first order was 2 /2.5 / 3 mm wick-didn't know what I wanted (along with kanthal 32)
so I just started cutting and wrapping and learning
started in the middle 2.5, worked OK (1st coil)
then just started cutting and mixing all the wick stock I had
so here is what my thoughts are (so far)
I'm NOT a believer in removing the supply (flavor) wick, I think it is necessary
I think 2 mm with kanthal wrapped around it is plenty as long as you have a good supply wick
in my experience the
ideal set up for the kanger bcc is
~2.5mm inside kanthal / 2.5mm supply wick~
then due to poor manufacturing tolerances if flooding and gurgling occurs,
install a larger 3mm supply wick in to make up the difference
it has worked in the wicks that I have built and I do it to the coil/wicks I clean burn
and just replace the stock ‘supply’ wick with 2.5 or 3 mm
so this is just what I have experienced and has worked very good so far and I guess will continue
to suggest it to others until I find a better way or am corrected by someone...
Happy
