I'm interested in hearing your thoughts on how your Huret Duopar handles as I've heard they are phenomenal derailleurs. I have the Sachs-Huret version on a Gitane that I just purchased this winter, although I haven't had the opportunity to try it out quite yet. Apparently, the Sachs version uses steel instead of titanium pieces. I've been told that these are still some of the best wide range derailleurs made. Great for touring when you suddenly have to go for the granny gear. They will shift from the smallest to the largest rear cog in one quick easy move.

Also, thank you for not only the higher res picture archive but the build sheet as well. That is very helpful for those are are on the cusp of building their own touring/commuting machines.
