This afternoon Sutliff 507-C, 3/4 bowl in the Peterson Pub with 9mm Blitz filter. Sublime but not long enough. Later Sutliff 507-C in a MM Mark Twain cob with long forever stem and a Dr. Perl Jr. 6mm filter to remember how the filter effects smoke for the filter thread. 14 mph wind all day so both pipes went a little quicker and hotter so I had to adjust draw accordingly and partially shield the bowl with my hand.
