Samysam13, you mentioned that your vape often tastes like metal, and I find the same thing happening. Since I don't think I require nicotine, I'm making a lot of my own juice. I've found that the Lorann's flavors taste a little metallic, so I'm using Capella's now (in California), which is wonderful. Their flavors are so true to the real thing, whatever flavors they claim to be. I love their Pralines and Cream, and their Graham Crackers is a close second.
I find myself rotating throughout the day between the Mint I get from Rocky Mountain Vapor, and a sweet non-harsh vape, my own no-nic Pralines and Cream, which I make with about 4ml of VG, 8 drops of Everclear (pure alcohol) (or Vodka, or distilled water), and 10 or 15 drops of Capella's Pralines and Cream.
I have a cold or flu right now so the Mint is too harsh for now, so I'm vaping the sweeter, less harsh stuff.
As for the juices we can get online, the tastiest I've had is Nhaler's Pear Lung, because its pear taste is not weak, like a lot of juices I find, but very strong, better than his regular Pear juice.
I'll never stop searching for my favorite flavor of all, which looks impossible right now. It was whatever I vaped in the Vanilla and Traditional carts of my first PV, the Njoy (Npro). All I can say is it tastes like there is Honey in there somewhere. The carts smell like RY4, which I do not like at all, but the taste at the mouthpiece is sweet, like Honey mixed with something else (still a mystery to me). Njoy does not sell their liquid, and their carts are too expensive to buy all the time, hence my search to find out if someone else makes a similar juice flavor. If I ever find it, it will be my all-day vape for sure.
I hope you can find a good juice you really like too, something that just far exceeds the norm.
