I've never tried either an Oom Paul or Churchwarden. Is there really a reason I should? Both shapes seem as if they would be a bit more difficult to maintain. I.e., getting the pipe cleaner through the curve of an Oom Paul or needing extra long pipe cleaners for a churchwarden.
Are they just fun or is there function to these pipe shapes?
