The African Flojo has a wonderful flavor that fits your description. A hidden gem. Very smooth smoke. I backed down on the amount of Nic seco and replaced it with more Flojo. It took the edge off as I found all Nic seco to be too sharp and edgy. It needed to be toned down a bit for my likes and Flojo did a wonderful job. Highly recommended. It is a viso but is NOT strong at all and has a subtle, wonderful smell. It's also a large, thick leaf so don't get nervous when you open the bag.
Another is the Aleman seco and ligero. VERY interesting flavors in both. The seco makes a beautiful wrapper also.
Here's one of my favorites... (52 RG)
Dom seco ... binder 2 half leaves (mild)
Nic seco... filler 1/2 (spicy)
Flojo... filler 1/2 (mild)
Aleman... ligero 1/2 leaf (mild)
Nic ... ligero 1/2 leaf (spicy)
Aleman seco... wrapper
If you want more spice then increase the amount of spicy tobaccos or, for a smoother smoke, increase the amount of mild components.
