Hi Linda--I hope you won't be disappointed--post some pictures. I snagged the 50cm Roadini on Riv's web specials page for my wife (it's currently somewhere in the midwest en route to us). Like you, she doesn't tour and I think a Hillborne would be overkill for her--enter the Roadini!
She has a Specialized Allez with skinny tires and 405mm chainstays. I think she's going to be blown away with the Roadini and won't want to ride the Specialized anymore.
Modern Shimano build (she wants brifters) but I'm going low gearing for our rolling hills with a 46/30 crankset up front and a 32t large cog in the rear. She gets my 35mm Compass Bon Jon's on A23's--it'll ride "like buttah." I'd have gotten a Sugino wide/low from Riv, but they aren't compatible with 11s.
I'll post pics and a build spec at some point in the process just for fun.
