You put up two U's so I was wondering what the comparisson was for... or was it just a typo?magruder wrote:BEN:
Not clear on your question.
The JD pipe has a nearly U shaped bottom - flattish compared to a more V shape to the Eltang and Comoy mentioned above.
The Heeschen has a similar bottom to the JD pipe.
