There is a direct correlation for me between hours spent in shopping for tobacco or reading reviews about blends and my tobacco purchases.
Now I just sit and smoke. I’ll visit online shops some other month
A pipe is like a coffee mug: can be tall, wide, short, etc. The caffeine is the same in the body.
But the shape does make a difference in the user experience!
However, I don’t think the shape will make a difference for the kind of tobacco.
Pipe cleaner after every smoke. Once in a long while, I use everclear or whiskey to wet the pipe cleaner and I run it through until it’s mostly clean coming out. If my pinky finger won’t fit in the bowl, then I ream it with a knife carefully.
