I have been ... fighting with this Dunhill Pipe since this summer. I bought it estate, refurbished myself, but it smoked like crap. Kept clodding, required many relights, when I finally had enough and I pulled out that long stinger - you know the metal insert that is quite specific for Dunhill pipes I understand. Smokes like a charm, very happy with it - in fact I wished I thought of this earlier, but I simply couldn't accept the idea that the Dunhill pipe "engineers" that designed the system designed it wrong. Have any of you guys had a similar experience with the stinger? Do you prefer to keep this insert or pull it out?
