My apologies! English is a beautiful language but one thing it doesn't do well is formal gender neutral pronouns.
Does coil ID affect the quality of the vape in a certain way? I went large because I knew the amount of cotton would restrict more of the chamber and I didn't want to choke airflow too mcuh.
The airhole on the Rose is small so I don't think any size vertical affects it. I felt though that the 2mm coil gave me the best flavor of the 4 sizes I tried. You may have a different experience though
