Really, so many. I don't even like Latakia but a couple times a year and usually it's one of Greg's blends.
I like many, but as far as what I stock up on for the future : Temple Bar, Union Sqaure, Cairo, Penny Farthing, Fillmore, Telegraph Hill and Stonehendge Flake (RIP).
It's the oddest thing I can't figure out - I don't enjoy C&D blends younger than 6+ months. The Virginias always taste young to me, or something that's not appealing. But Greg's virginia blends, I just jar em for a few weeks and enjoy em from then on. Not sure why the difference.
To put it simply if someone asked which blend to try, I'd just tell em try 3 blends that have components they enjoy. Chances are they'll find one they really like and probably none they dislike.
