What shape for what type of tobacco?

The best advice has already been give… smoke what you like in the pipes you like.

A couple of observations.

Tobaccos that tend to get bitter are better suited to pipes with squat/short bowls.

Many full bodied English mixtures, while they smoke fine in any bowl shape, seem more rounded and develop better flavor in pipes with wider bowls.

Load it up and smoke it, time will tell what’s best for you.
