Allow me to offer a counter-opinion.

I have a "light" touring bike, a Raleigh Port Townsend. It's comparable to the Jamis.

I have big heavy-duty tires on it (35 rear, 32 front) and two racks and I still ride it naked every single day. I've done centuries on it and I can still beat the 40-something's on $5000 CAAD bikes. I love my touring bike as an everyday bike.

At the end of the day, a bike is a bike and 10lbs doesn't make that big of a difference. Run thin tires and you might not be able to even notice a substantial difference.

The Jamis is not inappropriate for light touring.
