Totally agree with trying flavors you wouldn't expect to like! Alot of places have sample sizes - like Dat's Vapor or FreedomSmokeUSA, so you can try several flavors. Even if you don't continue to order from them, at least you'll have a general idea on if you like tobacco, fruit, bakery, etc flavors.
I'm not big on tobacco flavors other than RY4...but that's more caramel than tobacco, but it sounds like Backwoods Brew has good tobacco flavors from the reviews I've read. Right now my top three are RY4 (caramel/vanilla/tobacco) from FreedomSmokeUSA, Cinnamon Danish Swirl from Dat's Vapor, and a tie between Dat's Bubble Gum and V4L's Margarita lol I have about 50 other samplers that I like, but they arent a 'all-day-vape'.
Check out the Classified section for juices too.
It's a great idea to get several different strengths. I chain-vape alot when on the computer and enjoy having a low strength for that, but when that 'I gotta have nicotine NOW' craving hits, I like to have 24 or 26mg! My sister sticks with 24 or 36mg though, as she only vapes on cigarette breaks at both her jobs.
Once you have a fave flavor, if you order from somewhere like Dats or Tasty Vapor, you can get into using doublers - buy a 1oz high strength, and then order a 4oz doubler from the same place - that way you can mix a couple different strengths from the same 2 bottles.
