You could try the SS mesh wick. It wicks really well, and lasts a lot longer than the standard wick.
I have two Iatties, both at about 1.5ohms with mesh wick. I've been using them for a couple of weeks and performance is as good as new. I vape about 3-5 ml per day.
Stock wick only seems to last me about a day to a day and a half on my favorite juice before I burn it out I vape about 9-10 ml a day also at 3.7 and usually between 1.5 and 1.9 ohms.
I honestly think my problem is the juice I vape though.
Chain vaper lol and in all fairness there is probably about 1 ml lost in the wick whenever I change it. But I almost go through 2 5 ml bottles a day I thought I was mistaken but I am measuring with syringes.
How many cigs did you smoke in a day?
Changing coil does waste a little but in the long run you would come out way ahead. Especially with all the more expensive attys coming out. Not to mention when zombies take over and attys are all in china iatty will be right up there with guns and ammo on the must have list
Same problem here, medium vapor and bad flavor. After a couple dozen attempts I've given up, at least for the time being. Tried some of that nextel wick, more wraps, less wraps, different gauge resistance wire, all different voltages, vaping through the bad taste, dripping right on the coil(which does help some), widening the ceramic cup and upper plastic grooves, changing the way I draw. Every single time I couldn't wait to get a regular carto mounted back on.
If you get it figured out be sure to update this thread and let us know what worked.
