Yes to the Ribmo's. I received some from Panaracer due to a problem with a set of Paselas. The ribmo's are excellent tires, however they are the absolute most difficult tires I have ever put on a bike. I felt like I was wrestling a bear. After the first time, they've come on and off pretty easily.

As has been mentioned, they are grippy and feel more nimble than the paselas. Mine are 700x28.
