Microcoils and cotton are the bomb. Good to see from your sig that you are using awesome
batteries too. I am going to build a dual coil nano dragon coil for my next build, and also keen to try a riptrippers tinman coil build. The best thing about microcoils besides the performance is how easy they are to make. I have about 6 months of RBA experience under my belt but the RBDs knock their socks off. Vape hard and live long!!
