Touring in Italy - Pisa to Rome Via Florence and the coast

[epa611]

As the title says, we're thinking about summer holiday this year and quite fancy Italy.  Anyone any expereince for the roads about Pisa/Florence/Rome and any suitable places for inspiration apart from CGOAB?

Thanks.

If you use the secondary roads that follow the Arno you will not have a problem between Pisa and Florence. If you are going from there to Siena again the secondary roads are easy to ride. Don't know about the rest of your route.
