So I purchased a new RTA this weekend. Along with a tool kit which came with a couple really thin pieces of cotton. I built everything up and got the best flavor I've ever experienced while vaping. (I'm new though). It was giving alot of spit back so I figured it was the lack of cotton in my build. When I got home, I re-wicked with some thicker cotton a buddy gave me. Now I was using this cotton in the previous RTA I had which was sometimes giving off a weird flavor. Almost a burned cotton flavor but not quite. And I immediately tasted this in my new RTA. How much does cotton affect the taste?? What is a good cotton to use??
