Congrats on the new pipe! Let's see some pics, we all like pipe pics. Might make some of us jealous, but oh well.
Anyway, you might want to be careful dedicating a CUT of tobacco to a pipe rather than a TYPE of tobacco. I'll explain.
Not all flakes are created equal. Here are some examples:
-Virginia
-Virginia Perique
-Virginia Burley
-Virginia Latakia Burley Oriental
That last one is actually MacBaren HH Latakia Flake. There might be more out there like it. Latakia can ghost a pipe, as I'm told. So, you need to be careful.
Also, flakes can be aromatic. Peter Stokkebye Luxury Twist Flake is topped with something. Firedance Flake, Bob's Chocolate Flake, Vanilla Cream Flake all use aromatic toppings. And, there are some flakes that are deemed Lakelands, which can ghost a pipe too. AFAIK, traditional navy flakes were topped with rum, since the sailors loved their rum. Check out tobaccoreviews.com to see if the blend is topped. PS LTF doesn't mention any sort of topping on the package or blend description from the manufacturer, but TR lists some toppings.
So, my advice to you would be to pick your favorite flake / cake / coin / spun / navy cut tobacco, let's just say Dunhill Flake for example, and smoke DF or other tobacco in that genre only in your new pipe. So, Sutliff Virginia Slices would also be another lighter straight VA flake like DF. There could be other similar blends out there that are not in flake form.
Personally, I have 3 kinds of pipes: aromatic, latakia, and non-aromatic. In my non-aromatic pipes, I'll smoke anything that's not topped. This means straight Virginia, Virginia Perique, Virginia Burley. Haven't run across any Virginia with Orientals in it yet, maybe once. Some people have straight Virginia pipes, Virginia Perique pipes, Virginia Burley pipes, etc.
Lately, I've been toying with the idea of trying some non-aromatic tobaccos in my latakia or aromatic pipes to see how they compare. I'll keep the non-aromatic pipes "pure" for now.
I recently had a pipe that was designated non-aromatic, but I decided to make it a latakia pipe because of the bowl geometry (wide shallow bowl, prince shape). But I just remember how well I liked it for Peter Stokkebye Luxury Bullseye and Navy Flakes. So, I might switch it back. If it doesn't work out, it might stay a latakia pipe. But, the pipe was VERY well seasoned with VA tobaccos, it might not have ghosted. I may have only ghosted the cake. So reaming back the cake might help. If it doesn't, a ream down to bare wood and a salt/alcohol treatment might work. Or a retort, or GL Pease even wrote about putting it in the oven, something like "out damn spot!" was the title of the article.
Anyway, I'm not exactly sure how ghosting works, it doesn't seem like there's a specific formula to it. Some will say that you just need to smoke the ghost out. Might be a handful of bowls, or might be a hundred. Not sure. I guess it depends more on your tastes, and how sensitive they are.
Ghosting is different than souring. A sour pipe just needs a good cleaning, usually in the shank / mortise/ draught hole.
I guess I should have asked: what blends were you thinking of smoking in your new pipe?
Sorry for the long post. Stream of consciousness type stuff.
