I realize in thinking about an answer to this that i am highly seasonal in what I smoke, highly exploratory and very memory driven. I seem to hit a favorite and freeze it in a memory and don't want to sully the memory. OGS for instance: I took a tin to Europe a few years ago as the only smoke for a week visiting friends with my wife. OGS is locked walking perfect fall days in Amsterdam and southern Germany/France/Switzerland. I took some rando $30 pipe (because anything I travel with is sacrificial as necessary... I am not even sure I have that pipe still. I need to look!) OGS was also my introduction to age and tobacco, as not too long after that trip I met a guy at the brewery that came to our pipe night who shared several jars freely. 12 or 15 year old OGS: my mind was BLOWN. I knew OGS really well in that moment and was fascinated to taste in so transformed. The other thing he shared was Woodbridge, which also blew my mind. Never seen it since... maybe because the memory of the generous sharing is perhaps better than buying the tobacco ever could be.
All that to say... no clue. Burley #3, likely because I had 1 tin and smoked through it and savored every bowl? Or maybe I will just go with Granger and leave all the rest as memories of an amazing journey. And I don't think I have ever had it!
