I make my own twisted wires and have many new ideas everyday. However some builds are just too big. I have many rda's, my biggest being the dark horse rda, of which still can't fit some coils. I had am idea about a square rda with the posts on the far right or left side, thus providing more space for larger single coil builds. I can't find one anywhere. Do any of u know where I can get one or should I start looking into how to make rda'sXD
