A possible complication with sticking to one blend is that the blend can vary somewhat over time. For example, recent tins of GLP Stonehenge Flake seem to have less topping than ones from a few years ago. Still a great blend ... but a bit blander. I might be wrong, but I would guess that codger blends use more commonly available tobaccos than premium blends and keep their uniformity year to year by using more toppings. I smoked Captain Black White for years. I don't think I would like it as much now as I did then but it would probably taste the same. If you were going to stick to one blend, and wanted it to stay the same, you would probably be safer with a codger blend or one that was consistently topped.
