I only process and make my own blends and am always tinkering and trying something new. I do have a book of recipes in which there are probably 25 or so worth repeating blends, but I find myself not making new batches of old blends as much, mostly because some of them aren't really as strong as i like but they taste great and perhaps I'll make them up for some boys at the pipe club when the time comes.
There are endless possibilities with blending and processing, depends on my mood and phases i go through. Lately it's been heavy orientals with perique and more often than not i like complex blends with many tobaccos(kentucky, stoved virginias, perique, oriental latakia)
I always like to have a nice full english around(with kentucky and perique) but it's probably my least smoked blend. Or another go to blend of mine with kentucky, stoved va's , oriental and perique. But i have narrowed down my active jars of blends to only having around 3 or 4 at a time to choose from. I like to have something lighter, something a little strong and complex and maybe a powerhouse for those end of the day smokes, plus the English incase the mood strikes.
So compared to many people here, my choices are very limited, but always changing.
