One thing I might suggest. Your selections of tobacco (Virginia's, English, Perique's) keep you away from Burley based blends. I too, was staying in the same vein as you, almost exclusively and some friends, specifically
@Grangerous, helped me to expand my blends to include some nice Burleys. I have been smoking them almost exclusively for a few weeks and have learned to enjoy them.
A couple of days ago, I went back to try Va's and English blends and found that they tasted much more vibrant than I remembered.
I actually believe that just as with a balanced diet of food, having a variety of tobaccos in your rotation keeps your taste buds on their toes. Someone like

This is just my observations and with them and $3.00, you can get a cup of Joe.
