I'm using Kanger bottom coil tanks, Unitank, Protank, a few MT3's and vaping a 70% VG and 30% flavor and PGA. Is there a better way to rebuild the atomizer than just doing the same they did when it was manufactured? The reason I'm asking is because I have few that can be rebuilt and I've been getting quite a few dry hits even on the new ones. Backing up some, I was using a vision spinner for a few months @ 3.3 volts and it worked fine. Then I got a Vamo V5 and even at the lowest low volts or watts, and with a new atomizer, I'm get the burnt taste \ metal taste now and then. It usually happens after I take a few pulls back to back. I've put a couple of drops of distilled water in the mix to thin out the VG and it's helped some but it's not perfect. Right now all my coils are at 2.2 ohms. I hoping there is a better type of wick for the higher VG% or maybe I should try different gauge wire and wrap it more times to change the amount of surface area the wick is exposed to the coil? Or maybe just keep thinning our the liquid with water or grain alcohol? Feel free to get a technical as you want. I am assuming that the VAMO is using pulse width modulation to control the power and that is the difference between it and the spinner.
