I think Harris tweed is something you have to want all by itself. Meaning, if you want Harris tweed in a brown herringbone thats's a different thing than wanting brown herringbone tweed. I had a Harris tweed jacket for many years. Wears like iron, of course, and is beefy and warm. Eventually I, uh, outgrew it. After a few years, I sought to buy another, but found that my taste had evolved somewhat and I did not care for the bulk of the Harris tweed any longer. For my money, Glenroyal and similar bunches occupy a tweedy sweet spot at the intersection of texture and bulk.
Thanks for your thoughts, Andy. Do you think you would be of a different mind if you had to deal with real winters (i.e. snow and cold) and brisk falls? The Harris tweed seemed to better evoke the LL tweed posted earlier.
