Harris I think a lot of guys had similar experiences - the Danes particularly seemed to get shaping right before they got the smoking aspect really dialled in. I think most makers hit very similar tolerances today, but it seems to me like the American school really started hitting the "how do I make this smoke perfect" kinda before a lot of other guys.
Another way to say it is, some of us won't sacrifice smoking qualities for design (aesthetic) qualities, and some maybe will.
Here's a fun picture. Some briar. Top left heading down, 8 years old wood from Mimmo, 2 years old wood from Mimmo, and a block from Molina, which is the "whitest" supplier I have, and their stuff does darken some, but I've never seen it get really mahogany. Right column is some old (1980s) greek stuff - it's mahogany colored, through and through. Probably was darker wood the whole time, it's more heartwood than sapwood, tight grain. Below that is a block from Calabria I have had for a year and a half. Below that a block from Calabria that is new, very wet indeed. They turn brown from oxydation (you can see little brown edges peeking even on the ones I've cleaned up) on the outside.
The old greek stuff is the driest smoking wood, outright, it's dry as bones, and dead stable through environmental changes, it's like rock. Tastes .... kind raunchy, pretty earthy. The Italian wood is sweeter, more neutral than that. Calabria has a fine, almost waxy feel, where Mimmo's is sort of... ordinary, like, it's the benchmark for good briar. It all smokes fine though, and really I don't think if I made pipes out of all these blocks, there would be a ton of difference, with the exception of the old greek stuff tasting a little earthy for awhile, and the new wet block possibly not being ready for milling - but I'm not sure if I made a pipe out of it that any of us would be able to identify that pipe as being the wet/young block. Anyway just kind of a fun picture...
