I was looking at the wall of tires in my bike shed and noticed that I also have a Ziffiro Graphene 2. Very similar to the Rubino with slightly differing tread pattern. I rode my last Corsa until it literally started coming apart with over 7000 miles on it and never had a flat despite picking out bits of brown beer bottles on occasion. It wasn't even any good for the trainer which is where most of my smoothly worn tires end up.
