I have. (A few years back). The ride's crap and the handling's shit. And they're not that fast, unless you happen to have aero section wheels.
In the past year, I've used and abused a range of tyres. The fastest, without a doubt, are my 25mm Pro Race 3, running at 85/90psi. Hands down the fastest tyre I've used, and it's noticeable. I'm also currently using 23mm Open Corsa IIs 110/115psi, which serves as a good comparison, because it's widely recognised to be one of the fastest 23mm tyres out there. (Corsas for the dry, PR3 for the wet, though the PR3s are now on full-time). And it's not as fast as the PR3. Same wheels, same bike.
