As @jpmcwjr observed, I see that nearly all responses here list multiple blends. I think that evidences the sheer abundance of great English blends much more than everyone being unable or unwilling to settle on just one. It's a bit like eating potato chips in that sense.
I had to really ponder this one for a good couple of minutes, but I'll go with Peterson Early Morning Pipe.
The addition of "Arango"on Balkan Supreme never fails to amuse me. Whether it's Arango, Stokkebye, P&C, etc, it's the same blend. The brand name just changes depending on who is distributing it. It's the 1-Q of latakia blends. Some have even suggested that Danish made Pelican and Balkan Sasieni are it as well.
"Balkan Supreme" but most places always/still list it as Arango which is why I include it when recommending the blend so that it can be found more easily and also not confused with the Wessex Balkan Supreme.
