Pulled the trigger today. My tailor - William Field of Washington, DC - made a persuasive case for Harrisons' 14 oz mid-gray flannel rather than the Minnis. He thought the Harrisons would hold up better and looked better as well (the difference, to my eyes, were very marginal). Regardless, the need for a pair of trousers that could wear comfortably up to 60 degrees inclined me to go a bit south of the 17 oz fabric. I decided to hold off on the other commissions (light gray and dark gray flannel) until I've had a chance to assess these bad boys this winter. I'll be short of what I would like, but the mid-grays will get me through the winter.
