MacBaren's Virginia #1. If you can develop your technique slow enough to taste the sweetness of this blend without blistering your mouth, then you are ready to try other blends. Starting with any other blend is just riding with training wheels or starting with a big fat pencil, you will just develop bad habits. Nope, I suggest a clay pipe and one pound of Virginia #1, someone lock him in a room with these and don't let him out until he has finished.
Then after you have become a real pipe smoker, you will never want Virginia #1 again, and the world will be your oyster.
