"What makes this model stand apart from the rest of the series is the its super oversized 29.2 mm bowl to 29.2 mm diffused down stem. These larger pieces remove the “pressure point” that is the 14.4 mm or 18.8 mm bowl and down stem in most other bongs where airflow is restricted the most. Imagine a huge tube that is reduced to the size of a straw at just one point, it doesn’t matter how wide the rest of the tube is airflow will be restricted to the amount that can flow through that straw in the middle. That is why increasing the most narrow point in the bong can have a huge impact on drag. The one issue with this is that finding replacement 29.2 mm pieces will be harder then the standard sized but you can always find what you need online if not locally."
