I keep a very simple piper’s diary — pipe ... tobacco ... brief note on like / dislike. After a couple dozen entries, I can get a good idea if a given pipe likes any particular blend. If so, it gets dedicated. Some pipes seem willing to give any blend ago. I give these longer rests between smokes. If a pipe is too picky, I usually find it a new home. I agree with the POV that size and shape of bowl are the best predictors of what tobacco will do well in a pipe. I get plenty of blowback on this “What!You think you can tell how well a pipe will smoke without smoking it!” Bla bla, bla.
