I often mix and match tobaccos. Mostly it's because I have a bit left over from something I left out to dry but didn't all fit in the bowl. So I just mix that with whatever sounded good to smoke next. Sometimes it's 'meh' and sometimes it's really good... and sometimes it's good or bad just because of the way the blend hits me on a given day. I know this because I've duplicated a mix that I thought was fantastic one day only to find that a couple days later it hit me as OK at best. I do know I generally don't like virginias mixed with burley but once in a while even that combo surprises me.
I might go for something mild later on. Haven't been feeling 100% lately and tobacco hasn't sounded good at all. We'll see I guess...
