Just make sure that you have about 4 different “brands” of cigarette. With a different mix of the good stuff in each brand you can stay airborne at a higher altitude longer, or so I've heard.
While results may vary they are usually very good.
Back on topic yes I find that different sources each have a volume that sounds just right a bit to high or low and it just doesn’t sound right.
