I have some River bottom fog sauce...Have you ever tried any from here:
https://www.naturally-extracted-tobacco.com....
Oh yes...Ive had several from RBFsauce and got quite a bit when they stopped selling it. It was a solid NET line. And yes ive ordered many times from naturallyextractedtobacco.com -- he's a great guy and offers so much selection. Truly the superstore of NETs in my opinion. Ive been lucky enough to be able to try many NETs from many vendors over the past 3-4 years. NET.com (mentioned above), vash's extracts, a couple forum user's homemade, myvapejuice, goodejuice, heather's heavenly, want2vape, mt oak vapors, vaperite, and one or two others I've forgotten.
I've always looked for a certain flavor profile for tobacco vape juice, I guess. That smell of fresh tobacco, smell of a freshly opened pack of cigarettes (no ash or burning, just the smell unlit), the smell of an unlit mild/medium cigar. It's pure deliciousness.
Most NETs are good -- Ive found some that come close. Vash's confederate, and others like NET.com and goodejuice.com's perique, accadian gold, etc. I sometimes would mix Vash's confederate with GEF's Perique and Accadian Gold for a very nice flavor profile that was the closest I've come to my goal.
Now I am working on trying all the tobacco flavorings that are popular these days -- flavorah, inawera, hangsen. So far Ive got a few hangsen flavors -- ive enjoyed hangsen's Desert Ship especially. Also trying stixxmixx's NETs.
