50/50 is what I dig so far, but havent really ventured out much further hehe. I had to pick up an emergency bottle of the Vapin Plus liquid they sell at Circle K's last week and I could tell just by looking at it in the bottle it was way higher in PG. Its almost like water and just about completely clear.. I had assumed this meant the grape flavor would be popping out too but nope. Its not bad but I aint buying it again, especially for $8 a bottle. Who knows how long its been there though, the lady at the counter didnt even know how much it was til she rung me up haha..
Im gonna wait until I pick up my DIY supplies next week before I start experimenting, but definitely gonna try a tad bit higher PG mix, as well as a stronger VG mix with extra flavoring added too..
