I was really surprised ... still am a little ... at what a long smoke you can get out of a small bowl, even a Group 1 or 2, and flake/plug/rope tobacco. it just burns slower, even once somewhat rubbed out. With loose tobacco I usually don't expect more than ten or fifteen minutes. With flake, if I just sip along in the usual way, a bowl can go twice that long. I don't want to exaggerate, but at first, I intended to only have a quick smoke, like during intermission outside a music venue, and they were flashing the house lights and ringing the bell by the time I finally landed back in my seat after finishing a smoke.
