The only thing that makes the MM stems clench okay for me is they're soft. And the pipe use very light. If that same Stem design were acrylic and on a 55 great pipe, it would be horrible IMHO. Jack Howell does the best stem work of any pipe I've smoked. Rad Davis, Jose Rubio and Ryan Alden are right there as well. Thin, wide, relatively flat and a decent button. Try a really great stem and you won't be impressed with the MM stems.
