Got a pair of the 2.3" Dry 2's on one of my bikes, only ridden them about 4 or 5 times so far, but so far so good. They're grippy for what they are (reasonably soft compound helps there I think), roll way quicker than I was ever expecting, and they seal tubeless easier than any other non UST tyre I've ever used… When I pumped them up (with a trackpump) they inflated instantly, and even held pressure without sealant for a couple of hours! I just threw in a bit of sealant, and hey presto…
Oh, and look on the Bikeradar.com website, they got a 9/10 review on there! They're not meant to be an all conditions tyre of course, but seem surprisingly versatile given that they're marketed as a dry conditions only tyre.
