I like to chain vape, but that causes the issue of heat build up in the tank, which discolors the juice and seems to damage the taste of the remaining juice in the tank. SO the search begins to find a way or method to keep everything but the atomizer cool. I tried a SS wick in my Viva nova and genesis which given great taste until the SS wicked the heat into the tank. This is a perplexing problem for me. How to get great wicking without transferring wick heat into the tank. This is also the problem I am anticipating with the pyrex wick mod, which is why I havent tried it. I am not interested in dripping, too much work when I just want to relax with a good vape. Any suggestions?
