Make sure they say STERILE! I think maybe trying it in the pt first if that's enough for you to tell. Less actual contact I would think. I do my own pt heads in cotton and compared to a dripper its very little and its farther away from your mouth. Does that even make sense lol I get loopy this time of a.m. on my first morning back to work. I have had 0 days off this week. My dicktater says I have because I didn't work 2 nights but I came in during the day one one of them and the other I don't consider it a "day off" if you have to plan to be in bed by 6pm to get a nap before work at 11 on the day that is considered off. again I may not be making sense to anyone but me in this rant.
Pay no attention lol
When I had the issues with the cotton, it was the Protank heads with the cotton... When my Protank is working right, I use it the most. It just hasn't worked as well ever since I used silica heads. The cotton was perfect in it, especially with the Lavender Vanilla mixture. IT was my all day vape. It hasn't been replaced yet.
I know what you mean about "being further from your mouth" basically there's more between you and the coil, opposed to a dripper where it's right there and probably heated more. I liked the cotton because it retains moisture better than anything else I've tried. As I've said, the ReadyWick is good but it's not as absorbent. If the cotton ends up working, I'm thinking that a ReadyWick coil w/ a cotton cloud would be perfect. Best of both worlds.
