"Mild" shouldn't be a problem. I only made one foray into Stixx NETs and decided they weren't for me. H-Primed (or Havana Primed) was one of them, and the one I think you are referring to that uses the "stogy/stogie" reference.
The term "stogie" came from the American settlers, who crossed the continent, in Conestoga wagons. The wagon drivers would roll their tobacco in long slender ropes for smoking along the trail. In today's vernacular; stogie/stogy refers to long slender cigars, sometimes of cheaper quality. Outside of tobacco circles; it is a generic term for any cigar (think `40s Micky Spillane).
I personally found the Stixx I tried (Nicaraguan Seco, H Primed, Whiskey Cavendish, American Virginian, Aged Burley); all to be rather similar, and without inspiration. Whether it was a pipe, cigar, or cigarette tobacco... they all tasted much alike, and rather weak.
However, Stixx does have its supporters. I know
@Brewdawg1181 is one such fan. I will also freely admit I have not personally vaped any other NETs; so I have nothing to compare it to. Synthetic tobacco concentrates have been working for me. And, given their cheaper cost and lower rate of coil gunking, is where I will likely stay. I also freely admit that my own wonky taste buds often don't agree with the common opinion, and often seem to taste things differently than many/most others. So please, take my opinion with a huge dose of skepticism

.
By all means, give Stixx a try... you may find you like them. I would only recommend (as I do for any untried concentrate), that you buy the smallest bottle(s) to start, until you learn if
you are going to like them. Then, if they are a personal hit, you can buy larger more economical sizes.
