I am new to the sub-ohm arena but have been vaping a little over two years. Sunday was two years since my last cigarette! I have been mixing my own juice for well over a year and have found that a 70 PG/ 30 VG mix works best for me. The higher VG juice gets me coughing up phlegm in less than a tank. I have been researching the Temperature Control threads and sub-ohm building threads. Most people are talking about high VG juices. I do hope that those folks are just cloud chasers and it's not a requirement for sub-ohm/TC vaping. I have a Sigelei 150 TC and a Lemo 2 on the way as we speak (watching for vape mail). If you are into the sub-ohm thing and particularly TC, what are your thoughts on the PG/VG %? I'm going to do what tastes best for me anyway, but just curious. Thanks.
