Ahhh... I am late to the battle, but this here is also another great hill to die on.
If you don't think that there is any significance between smoking a small cone shaped bowl and a large wide U-shaped bowl, then please just stop talking about any tastes at all. You obviously aren't tasting.
This is absurd. Why would they even have tiny .5" wide bowls and 1" wide bowls? It has been posted many times over the years that you can smoke a small bowl just just as long as a wide bowl, the differences in amount of time needed is the Hight X Width dimensions, not just the overall volumetric size of how much tobacco it holds.
Think about small diameter cigars verses wide ones. The volume of smoke, the amount of surrounding tobacco that contributes oils to the smoke, and how much of each type of leaf in the blend is contributing at any given time.
If you are talking about the differences between a .8" and a .9" wide bowl, then get out of here. You don't even have a good range to compare.
But, with a tall narrow cone shaped bowl, I can focus in more on the flavor of a single leaf blend. A wide shaped bowl (at about .9-1" wide, the shape becomes less important) I get a more full amount of smoke that absorbs less into my system with each sip.
I have to say, if you can't tell a difference in the smoke coming from a .6" wide by 2" tall cone shape and a 1" wide pipe, then you're not tasting. Why the hell are you here? Stop arguing with the big boys, set down and learn something.
The two diametrically size and shaped bowls will not give you such a difference that you will think that you are smoking latakia in one and a straight Virginia in the other. But in a wide bowl a Virginia can become more mellow, but the delicate nuances of flavor get lost in the volume. Like tasting honey before making a mead, you only put a drop on your tongue. If you stick the whole spoon in your mouth you'll never be able to tell an Orange Blossom honey from a ragweed. Sipping delicately from a tall narrow pipe, is more bitey and acidic, but it allows you to pull the more delicate hays and citruses, etc...
But, for my everyday smoking of Virginias, I do tend to go for a medium .8" sized bowl. It seems to give me less bite with still some of those delicate flavors.
I don't usually enjoy a latakia in a tall narrow bowl. It's not absurd to me, but it just doesn't give me as much enjoyment as large volumes of smoke as a larger pipe bowl does. However, when I smoke a new to me tobacco, I will try different pipes, shapes and sizes.
