I recently ordered MTS Vape Wizard from My Freedom Smokes for use in my tobacco blends. The MTS sands for mellow-thick-smooth, it adds a depth to the base flavor without imparting it's own flavor, but the enhancement is awesome. It also takes some of the sour or acid taste out of the mix. I really do recomend this to anyone who vapes tobacco juices.
I also hear this is good with darker flavors like vanilla and coffee.
