OK, built my Mini with claptons at .3 ohms. Not as low as yours, 5 wraps at 3mm. I wicked it with organic cotton from a cotton ball and it tastes fine.
I usually start low on the wattage and move up in 10-20w increments. so on this build I started at 40w and then went to 60w then to 80w which is really too warm for me, but tried it anyway. It tastes fine, warm, but no dry hits or burning.
I'm not here to tell you how to vape, but 80w is hot by nature (especially with the mass of wire you are using), and too hot for my taste - though I know it's not unusual, just personal preference on my part.
Do you get the same bad taste/dry hit effect when you try a lower wattage?
You might want to try starting lower when your cotton is new and increasing it slowly as the cotton breaks in, and keep your wicks wet. Other than that, I'm out of ideas, sorry.
