Was just trying to help, since a definition of 'Clyde style' and your question of "What makes a Clyde style fly a Clyde style fly?" have still yet to be answered other than "The last page shows the crucial differences"
Since Don's own website has a link on the main page of the site I posted, I figure Don himself endorses http://www.thehighlanderway.com/index.htm
FAOL itself also has a link on that site's main page.
