Never heard of FF till now...
The F is my least favorite of the bunch, and I personally think it is 'weaker' than the regular Cain (what some refer to as the 'Habano')...
Daytona is more complex, especially in the 6x46 Corona...
The most boring of all is the 6x60 F...
The Cain Maduros are just meh IMNSHO...
I do like the Connie robs now and then with a pot of coffee in the AM...
All of the Cain Nubs are washed out to my palate...
