soooo I was complaining the other day in the innokin thread about the z coils and one of the most important things I was crying about was that they claim u can use with 70vg and in my opinion the cotton is very tight in there to wick well like the first day it's ok but the second already u see drop in wicking performance and u need to wait for the cotton to get ready every 2 puffs or something....ok I know many say they have no problems and it's not I get dry hits but my juice it's not even 70vg its 66% vg and I see it lose vapor after first puff and also sometimes wierd flavor.....aaanyways if u work 60vg in my opinion works well and ok I was thinking it's actually impossible to make a stock coil to work 60pg without leaking and also 70vg perfectly I guess... like ok I get it they do a good job...sooo anyways I rebuild my z coils now and I can adjust the cotton, the airflow of coil and use any wire I want and they are perfect for my 66vg juices....Soo I was wondering...has ever any manufacturer made coils besides the wire also for different thickness of ejuice?? Like for vg pg percentage??? P.s. sorry for my English i i i hope u understand what I try to say
