No way for me to pick just one ... I tried and it made my brain hurt. 8O
So, I'll just throw out a few models and what I like them for.
For longer smokes and/or "big bowl" blends - Country Gentleman, Mark Twain, Diplomat (love the apple)
Medium length smokes and/or Va's and Va/per's - Legend (love my Rob Roy) and Washington
Short smokes while at work, running errands or sampling - Morgan, Eaton and Tom Sawyer
There is some cross-over between the first and second groupings when it comes to certain Va/per's and English blends.
I would say that the one I've reached for the most, recently, has been the Mark Twain.
Flakes consist of a large part of my diet and the Twain smokes them nicely. :
