I bought the Rig V3 with Terk RDA today and I'm loving the mod with my Subtank Mini. However I would like to also love the Terk. I have only tiny wisps of vapor. No mouth feel whatsoever. It's flavored air. I wrapped the single coil to .5 ohms like I use on the STM using 28g kanthal. Plenty of cotton, plenty of juice obviously because it tastes great. I don't know what's causing the problem. Is it the unrestricted air flow? Any suggestions on how to fix this would be much appreciated!
