Thinking about it overnight, knowledge is power in this case. And you can gain a lot of knowledge at the manufacturer web sites.

E.g., Giant offers a lot of information on their bikes. If you go to the links and then click the tab for geometry you'll get plenty of info about how their frame sizes interface with inseam length.

Giant treats hybrids under the category of Lifestyle bikes:

And the fitness bikes are under the Road category:

Based on handling, speed, and quality I love my TCR, but my next purchase will move me in a more "comfortable" direction.

If I stay with a DF model bike that will probably be a Giant FCR, or something in the Trek 7.x series.

Otherwise, I'll fall over into the dark side and buy a recumbent!
