Never really got into forums but as I get my answers from you kind folks that post on places like this I thought I would sign up and pass on some my coil building expertise to others. I have had much success and failure using multiple build decks on various RDTAs from my first old tfv4 up to my aromamizer plus with the trusty obs engine and the ijoy limitless combo using ss, and kanthal a1. Along with various regulated mods using 18650s and now 20700s
