Perhaps some examples? Unfortunately, people can use the same terms to describe totally different things, and/or may describe the same characteristics in completely opposite ways. The more objective context you can provide, the better.
I am fond of the Halo tobacco flavors: Prime 15, Torque 51, and Turkish. I also like Voodoo, but it's not one that I really associate with tobacco.
You're right. It's so hard to describe flavors, especially with the whole 'taste is subjective' thing!
My least favorite, and the one that tastes most 'leafy' to me is Ahlusion's Sahara blend. I also find that flavor in the Plume Room's Honey Fig tobacco and Arctic Cowboy, Vapor Chef's plain tobaccos and menthol tobaccos.
I haven't tried many others because I have already wasted a lot of money on juice that is unvapeable for me. Also, I live at least and hour away from the nearest b&m where I could actually sample juice, so that's not a very convenient option for me.
The ones I do like: any of Nicoticket's tobacco blends, and 15 Foot Falls and Pear Ship from AiV. Actually, I didn't like Pear Ship that much b/c the pear was too strong, but I really liked the tobacco in the background. These are all NET's, I believe.
