I feel 'sorry' for you guys who know about pipe tobacco, enjoy it and still feel the need to reach for a nail.
To answer the OP's question with my opinion, I'd say get a tub of one of the major codger blends and stay with it for awhile...the one I used was Sir Walter Raleigh. I still enjoy that and Carter Hall and Prince Albert...although, I will say that I recently opened a fresh tub of CH and that first bowl seemed to dry out my mucosa...Virginia tobaccos in flake form can be tricky for those uninitiated and who tend to draw too deeply, but they offer a nice flavor. You can use them cubed or rubbed out along with a codger for a more zesty bowl.
Ultimately, a flake will be most flavorful when kept rather intact. imo.
