I don’t have a specific blend that I fall back on. In fact I have very little in my growing cellar that is 4oz or more.
I would say, though, that there is a style I tend to fall back on: English ribbon cut blends. Some that have never tired: Balkan Supreme, Super Balkan, Stratfordshire, Presbyterian, EMP, or my own home blend concoctions that have a nice balance of Virginia, Oriental and Latakia (with the occasional sprinkling of Perique).
For variety I pick either a light burley-based aromatic, or a straight VA (flake or ribbon).
