Everyone has preferences on a certain style of bong bowl, aka bong slide. Many users prefer that the bong slide has a single hole, creating optimal airflow pathing to pass through all your herbs and burn them evenly. Single hole slides are also commonly used for "snaps" in which all the flower is pulled through the bowl after its been burned. Single hole bong bowls and slides are the best way to go for newer users and users who prefer high airflow, and want an easy to clean bowl piece.
