There is a weird thing that happens if you smoke the same blend twice in a row (or more). Each time you smoke the same blend, you taste it less each time. This is why I am always switching between blends. I also start my day with an aromatic, and then smoke Virginias, and then VaPers, and then maybe a burley or two, and then if I am going to smoke latakia or Dark Fired, I do it just before my last bowl of a strong twist. This way I am moving from less taxing on the tongue blends to more flavor throughout the day. This, and then drinking water and coffee, and maybe some sliced fresh fruit between smokes to refresh my tongue. And, keeping a clean pipe is key. +1 to Woods.
Works for me, YMMV
