I don’t feel a need to store stem-down to enhance drying but I don’t generate gurgles too often when smoking. Exhibit A is a lousy rack as it practically necessitates upside storage of bigger pipes or ones with bent stems. They could have easily designed this out by raising the height and giving a bit more space between pipes.
Exhibit B is way better - the pipes just lean in there and it accommodates every shape and size I own
