I have nothing but kayfuns and clones or protanks. I am wondering what setup you use for testing out your recipes. I am going to start doing my first recipes in the next week or two. Most are shake and vape. I've never used a dripper but it seems that would almost be the ideal setup for testing. Then again I know say going from a protank to a kayfun can change the flavor tremendously. What's your favorite way to test?
