Frisco is a tobacco with hazelnut (to me) flavoring.
These are analog-tasting and not sweet at all.
They are made with tobacco extracts but are not "naturally extracted".
The 'musty' tobacco taste sounds like "Turkish" flavor. AVE's Kamel has a bit of that. Dekang Turkish Blend has a buttload of it.
I suggest going ahead with a purchase of Boba's Bounty because I've found it very useful for blending with sub-par tobacco juices to make them more palatable. Sounds like you have a few of those sitting around.
That sounds like a good idea. Plus I'm long overdue for placing an AVE order. I really wanna try the gorilla juice too. My only worry with AVE is how they'll perform in cartos...
