Wonder if the Vivente might be a little heavy duty for the light touring the OP says they want to do.
I've developed basically two bikes for touring now. A 700c road bike for fast light long distance hwy use and my converted 26" mtb which is slower but a good heavy duty mule to do both road and gravel. If I want to pack stuff or go off road I like it but I know when I ride long distance I have often wished I could go faster, lighter (hence the second road bike for that purpose).
I have been looking at the Surly Crosscheck as a "one bike does all" option should I ever want to downsize. Road worthy but able to take fatter tires for gravel.
