Just getting around to commenting on the ride of the Vittorio Next TLR. My first ride was 82 miles on everything from really good pavement to really bad; more of the bad than the good. I don't find them as supple as the Pro One Addix and they definitely don't roll as well ( I really noticed the chipseal). Not horrible though. As far as handling goes, they seemed fine for my needs. I'm not pushing the envelope on high speed cornering. These are non-directional tires with just straight grooves so would not expect them to be great in the rain but the bike I have them doesn't get ridden in the rain.
The Pro One's are still my favorite tire but for the money, these are a good value.
