Not familiar with dunhills. I'm buying up all the Virginia I can afford. I believe the reason you must sip slowly and savor the smoke is to be able to taste the more subtle flavors of that tobacco. Tongue bite may or may not result, in my experience, if you puff too fast but you will surely miss all the flavor possible with each blend. Trying va/pers is another way to ease into straight Virginias. I started out that way but not on purpose. It just turned out that way.
