I've been vaping nearly 2 weeks and haven't smoked in 9 days. I started with a vpark tc70 with maxtank pro, I couldn't really get what I needed or wanted with it so now for the past week I have been using the coolfire iv tc100 with smok tfv8 and I love it. I did try a camel filter a few days ago but it stunk so bad and tasted 100x worse I couldn't hit it without gagging and I smoked those for the last 9 years, marlboro red for 6 years before that. I've tried 3,6,9 and 12 mg/ml and I can't decide if 6 or 9 is the best balance for really good flavor and enough nicotine after a few deep lung hits. The main guy at the local vape shop, which my small town is extremely lucky to have, told me how he mixes his juices to be a true 70/30.
