PT-50 or Parke Offenlach?

[Tubman]

I've been the happy owner of a PT-50 mouthpiece for about two years now, but I've recently come in contact with a large following of Parke Offenlach users that swear by them. I am thinking about borrowing one from a friend that is a part of this following and would like to inquire about the benefits of the mouthpiece from more people who may have had different experiences so that I may get a good idea of what to expect before I try it and wonder why a certain phenomenon is occurring. Have at it y'all!
