I actually have made one tobacco flavor that was pretty good right after mixing; a virginia with hints of apple cider and cinnamon... unfortunately, that was right around the same time I got totally sick of the virginia tobacco flavor, and went almost entirely over to sweet/fruit/dessert flavors. But if you like Virginia tobacco, I highly recommend Tobacco Express Virginia -- not Golden Virginia, but plain Virginia; the Golden has that "vegetative" sort of taste, which to me tastes a lot like the smell of celery that's been left in the crisper drawer till it liquefies -- yechh!
My ADV for over a year now is my strawberry & cream -- massive gunk monster, but so tasty, I switched to RDAs from tanks and just dry-burn/re-wick every other day or so.

The flavor is worth it.

It's 30% flavor, so it's vapable right away; best after about 3 days.
But every other juice I've made that has any tobacco flavoring at all, is vastly improved by a 3-6wk steep. Tobacco is just a really subtle taste, and takes a while to fully develop.
