I agree with Tameiki, I want to see you do well. I was at 50/50 but went to 60/40. It's a very good vape and does the job for me. My gear is the Tesla with 2.2 ohm cartomizers. The juice has been the tricky thing. I have dropped the nicotine level to 12 mg and plan on dropping to 6 mg. I recently got the texas tough tanks but have not worked with it yet. Personally vaping is a work in progress. You are in a good place to learn a lot.
