OK, I have read a lot of information and I'm not quite sure how much flavor I should add. What I mean is I'm using eliquid calculator (the one with the penguin) so where should I start as far as percentage? I noticed I like my e juice flavor a little stronger than most store bought e juice. I was thinking a total of 15% flavor to start, but I'm not sure if that is too much or too little. Any advice? I'm going to mix 70/30 VG/PG with nic of about 8 to 10. I don't want the strong throat hit so that is why I like the 70/30.
