Looking for a light tobacco taste, nothing "dark"
Well TFA RY4 dble works for me..... and FA Cuban Supreme is a Great stand alone @ 1%. ( Dont let the name Cuban Supreme fool ya, its more like a light tobacco.. maybe vanilla like sweet taste.)
Both of these also lend themselves to slight adds that complement them, like a bit of Toasted Almond or AP (in TINY amounts! ).
What I find with my use of tobacco concentrates.......
All most all have a sweet spot percentage wise, and many over shoot when mixing. ( Then try to tame it with adds, and end up with Franken Juice !
).
When using flavors to "enhance" Tobbys, it should be soft nudges with "soft" flavors... Not bold percentages with bold flavors.
Exceptions are when you throw the idea of "Tobacco" flavor out the window, and use it in something totally unrelated to tobacco.... like coffee.
You dont really expect to taste tobby in your mix, you want coffee...... but the tobby compliments the main flavor.
All just MHO.... YMMV....
