I'm actually a bit of a black licorice snob, when it comes to the candy. And you're sort of correct, black jack gum is mainly black licorice, but it does have a hint of clove, or something else that gives it more spice. Likely just another ingredient that goes into BL, but I can see where you got that.
I wasn't sure how I'd feel about a BL vape; even though I'm a huge fan. I was actually worried that they would suck, since I actually hate 9 out of 10 BL candies out there....like I said, a bit of a snob about it. But I tried Mount Baker's, and it's dead-on-perfect. I usually try a few different brands before committing to a vape, but they nailed it so well. It's close to a good n plenty, if you're fan of the candy.
Anyway, I'd recommend trying MBV's version. Oddly, I haven't vaped it yet after trying the one taster....seems like a bit of a tank commitment, and as much as I love BL....I fear that the tank I put it in will never be the same after switching flavors.
