The GRAV® Hammer Bubbler is the tool for the job. (If the job is jumbo hits and a super easy-to-clean design). The Hammer has been redesigned with a wide 38mm can, so it rests easy when not in use. A fission downstem diffuses smoke through 0.5” of water for cooling, and it looks good doing it in a variety of comely colors.
