I am also a protank lover,
2x protank ones
1x protank v2,
At the beginning, i realyy most of the time hated the protank, new coil, cleaned coilt etc.. most of the time that damn burned taste ,
or gurgling ,
Since i recoil the orginal coils, im in love,
most of the time i make micro coils (1.8/2.0 ohm) and use it with bio cotton /silica /bamboo wick etc...,
with all of them i get realy good taste, and minimal burned taste,
I never use extra flavour wicks !
my allday vapors mostly 60/40 or 50/50 (pg/vg).,
By the way with non recoiled coils, good taste too, (not often but sometims burned taste )
because the micro coils is stronger and easy to switch the cotton/bamboo i prefer micro coils.
(and excuse for my English )
