Hi, I am new here. I am looking to get an RDA but not sure if I should start with a single or dual coil RDA. Right now I use sub-ohm tanks and typically vape around 40-50 watts. I don't like a very warm vape because it tends to hurt my throat. I am not sure if that means I should start with a single coil or if I can run a dual coil at 50 watts. Any advice is much appreciated. Thanks!
