One other item on smok coils. The "new coil" taste. When you get a new smok tank, the pre installed coil is fine. Proper priming and youre ready to go. But then, when you install a new coil head, there is a funky taste through the first couple tankfuls. Ive read several accounts about this and explanations vary from juice flavor issues to wattage. I have decided that it is simply a "new coil" taste. Probably a residual machine oil or something. I havent tried it yet but ive considered soaking new coils in everclear for a few hours and then rinse and dry thoroughly before using. When i do this, ill report on the results. Just my two cents worth on this issue.
