My favorite for a while has been Johnson Creek. They're tobacco flavors are awesome. A lot of flavors attempt to mimic an analog. Some come close, and they're definitely tasty. But I've found my favorite "tobacco" flavors to be the slightly sweet, toastier ones such as JC original and tennessee cured, which now comes in 100% VG. I prefer the JC tobacco flavors over BWB, which are still quite good.
I also just put in an order at FSUSA for the first time. I have high hopes for those given the reviews I've seen. I prefer almost all VG with a little PG, which FSUSA lets you "tune" for certain flavors in 10% increments. I did 70/30 VG/PG. I do 6mg or 11mg nic content depending on the vendor. I was a half a pack smoker and I find that with the amount I want to vape, the higher nic juices are too strong.
