Thanks, RL and pd. I appreciate your input about fitting.

The thing I found odd was that bikes, particularly the endurance style bikes, are so similar in their measurements (namely, reach). I found it odd that the 56cm and 58cm Scott Solace only differed by about 5mm in reach and about 20mm in stack. For me that made it relatively difficult to decide between similarly sized bikes, and the people at the shops seemed just as perplexed as I.
