I have a consistent tobacco rotation, and it doesn't vary with the seasons (San Diego has a mild climate year round):

Dunhill Flake
F&T Vintage
Escudo
Capstan Medium (blue)
Solani 633 vaper
F&T Cut Virginia Plug
Solani 656 burley

The two Solani tobaccos are new in my rotation (and excellent), and I don't think that I'll be ordering any more F&T Vintage or Escudo.

I also have some FVF and Wessex Campaign with good age on them that I smoke on occasion. And I try some new-to-me tobacco from time to time.
