When time is limited, should you pack a full bowl and relight it throughout the day or should you pack only small bowls that are smoked entirely?
My recommendation would depend largely on the type of tobacco being smoked (and, of course, your own personal preferences). Some tobaccos work very well on a relight; the flavor and aroma seem relatively unaffected by sitting in the pipe for a while after being partially smoked. With these tobaccos, packing a full bowl and smoking it in increments throughout the day should work just fine. You'll need to experiment with relighting your favorite blends to see how they taste, but I recommend at least dumping out the ashes between relights.
For tobaccos that do not respond well to relighting, such as those that produce a nasty "ash tray"-like flavor (or worse), I recommend going the small bowl route. That is, just pack enough into the bowl for the time you have and smoke it up. I do this frequently when I have limited time. Even if the tobacco would relight well, I sometimes do not wish to carry around a partially filled pipe.
In either case, I recommend simply doing what works best for you. There's no "right" or "wrong," but only the practical matters of convenience and enjoyment.
