I think many will have more than one favorite form. If you still keep the rotation, and have a pipe for each mix of tobacco. I would say that I don’t have a favorite shape, rather a size KS.
Same here. I usually prefer a larger bowl to a smaller one (to a point).
I love both the form and function of a poker. I have a couple of Savinelli 311KS, which I find to be a well balanced example of the shape and are probably my favorite briar pipes.
What kind of tobacco do you prefer to smoke in the KS?
I tend to smoke Englishes in them. Current favorites: Presbyterian, Father Dempsey, Sutliff Match 965. But I also will load them up with a burley, DFK, or Balkan and they perform admirably. They only things I don’t smoke in them are aros and Virginias; I have other pipes for those.
