Hits go down better.
When I have my choice, I choose NOT to smoke a Pipe. This is because, with my lungs (and a little Asthma), I never seem to get a full, solid Hit. I have 2 problems: (1)Usually, I am sucking away on the Pipe for half the time, justto get it flowing well, and (2) The Hit is more harsh (especially on a Wooden Pipe), and so I frequently end my Hit a little earlier than normal.
The Bong is Low-Maintenance. I lightly inhale, and keep inhaling. The Hit comes smoothly, right into my Happy Lungs. I like BIG Hits. So, a Bong is a BIG hit with me. Also, because of the easy air-flow, I am less likely to cough (a Fun benefit).
Actually, I love the Romance of using a Pipe. When I use one, I remember that people have been smoking marijuana
like this for century after century ... and Here I am, re-creating an age-old Tradition.
