It's an interesting thread to read.
There are connoisseur pipes, there are grass roots pipes - and they are not equal in many ways.
It's not that smokers cannot get a good smoke in a grass roots pipe, and it's not that a beginner will not have the possibility to get a bad smoke from a connoisseur pipe. There is something more to it.
To understand, let's think the most hyped beef in the world - Kobe beef. From the breeding lineage records down to the exact identified cows, from the meals and massage every week, to the mature time for the optimal marble patterns, these are all monitored by highly trained individuals. And then there is the years of apprenticeship for another individual that enables him to divide the cow into different parts for specialized ways of consumption. Finally, there is another long ladder of strict apprenticeship that the chief has climbed up so he is now responsible to select and cook the Kobe beef in front of the customers. This is one kind of enjoyment.
One may say, the street wok fried beef he enjoyed in a random country during his SE Asia holiday tasted really good to him. Those are his taste buds, I just have to agree. It could be that the street food seller had been selling street food for 10 or 20+ years and he instead of his standby workers was working that day. But it's still a different kind of enjoyment.
For a pipe manufacturer, such as Barling, that was responsible for creating smoking pipes for generations of reigns of the royal family, do you think they allowed workers who were not trained to their standard to produce pipes for the market? How about the sons or daughters of some artisan pipe makers, what amount of training they have gone through before their fathers agreed that was about time to have their debut pipe sales? Of course, the renowned MM cobs also have standards and quality control, but I believe their standard is different from say, Barling, or Dunhill. This is just my opinion.
That being said, I have always been thankful to pipe manufacturers who create affordable pipes, so that beginners can try out pipe smoking more easily. I usually gift younger fellows to whom I introduced pipe smoking a MM cob with a pouch of tobacco - MM makes these present more affordable and I don't have to worry what they do to the cobs.
One kind of pipes similar to MM cobs that are also affordable have been dying out. There used to be quite some people making pipes from cherry tree in Austria, but I have not (yet) heard of any maker exists as of today. They are the cherry wood pipes. They can smoke really good, if not better than a MM cob.
For the "cherrywood" or cob looking Dunhill above, I own one example. That shape is actually called 'Don', a variant Dunhill created after the shape 'Duke' that Dunhill designed for Prince Edward, Prince of Wales.
Perhaps he gave up his throne also because of his love of pipe smoking:
I own no 'Duke'. This shape has no shank, resembles exactly the traditional cherry wood pipes and corn cobs. One may say, a pipe made like a grass roots cherry root, but with selected briar and by Dunhill's craftsmen - Voilà, then it becomes a prince's pipe, his favorite shape indeed according to some legend. Older models have usually the stems made of bone. Perhaps I may get one in the future, if I get into PAD again.
