Very interesting post.
I checked up on Telescopes tobacco, and apparently there is some copyright hassles going on with it right now, and if it was available to me, I'd try it for the reasons you state. I've been using Smokers' Pride Whiskey for the same, it being as close to neutral anything I have. Any flavour it has is to me, very undertoned, and it burns fairly hot, and is better for breaking in pipes than anything else I have. Once broken in, I then dedicate or bias the pipe to a particular blend or type. I find Lats the most ghosting of all, but as I don't mind them at all, they get smoked in their own pipes.
Any strong opinions I have are long gone except for my personal favourites, which at this time remain the same. Hope I'm on the right track. Any suggestions you or others have would be most welcome.
After 40 years, I imagine it's all in the public domain by now having failed to file a copywriter for the name - damned, what was I thinking back then.
But yes, a tobacco full of black Cavendish is absolutely great for breaking in a pipe and as has worked for me over the years, keeping ghosts at bay when used alternatively between tobaccos that ghosts.
Although I have more than enough pipes to dedicate to a specific blend, you see, I am lazy and in fact, would hate to see a pipe have to wait to be smoked until I decided to light up a certain genre of tobacco. So it has become that while I do smoke a great variety of tobacco blends, every other smoke is generally one of these -
Telescopes, Lazybones, EZ1, The Doctor's Own Blend, or Black Maria. I note that
Black Maria and The Doctor's Own Blend while containing latakia in them, have it at a reduced level than most English blends.
All of the above tobaccos have a generous amount of rich black Cavendish added into their mix and the flavors don't ghosts. By alternating them with other blends that do ghosts, I find I keep the carbon cake fairly exorcised of nasty spirits that might otherwise force me to either deep clean the pipe or dedicate it to a specific blend. Since I smoke a lot of latakia blends, this works for me.
