tslots.......Indeed, sir, a reasonable question / observation! In my case, I am affected by two elements: (1) By "doing justice to a pipe", I am expressing my own personal habit / approach to the pipe, in that I always smoke a reasonably large bowl, and enjoy a slow ritual of packing the bowl, lighting, smoking slowly, savoring, etc., then cleaning the pipe-stem, etc., etc. Invariably, during the day, I find myself rushed, and savor a small tobacco / nicotine rush while drinking coffee, but frequently without the time needed for my own approach to smoking a pipe; and (2) I also truly enjoy cigars !! I admit it; I am a "switch-hitter", with an AC/DC approach to pipes and cigars !!! However, your point is completely valid, and I would not disagree that a small bowl, or a less than full bowl, can be a fully satisfying smoke. For me, a couple of cigars per day, and generally three pipe-bowls per day, and I am happy !! I do also admit that I have never fallen into the habit of cigarettes! Regards.....Nero
