Hi, my xl is arriving today and have watched some videos as am interested in building on the two supplied decks, but have got a few questions, and am hoping you could point me in the right direction. I really am not sure what wire to use to build the coils for this tank, I see so many different types being used, for example should i use kanthal or clapton? , does it really matter ? .Am i best to buy pre built coils and if so what type and what resistance coils ?. When you make your own coils and use pre made how do you work out what wattage they should be vaped at. Please treat me as a complete noob, because i am. Thank you for your time .
