I'm running 25mm Vittoria Rubino Speed G+ tires paired with Continental Race Light tubes on my road bike. They are very supple and roll fast, never harsh or twitchy. Acceleration is great with Dura Ace C24 wheels which weigh only 1360 grams/pair.
Only about 500 miles on them and I'm watching them like a hawk, inspect them after every ride. So far I have not seen any cuts or signs of excessive wear. I am very careful where I ride and the country roads in North Georgia are generally clean and silky smooth. Hopefully they will just wear out rather than fail.
In terms of ride they are definitely as step up from the Vittoria Rubino Pro III Slick (non graphene) tires which I used to use exclusively. I'd be more concerned about durability if I still lived in a place with poor roads.
