I've used X-2 pedals for 8 years or so - the unrestricted feeling was a little like being on ice at first, but I got used to it quickly. I'm on my third set of cleats, and will likely get a fourth this year, but that's mostly because I'm not diligent about bringing my cleat covers when I ride. Very easy to lubricate, and I rebuilt a used pair with new bearings for my second bike. +1 on the dirt issue, I had a little bit of wet sand give me a lot of trouble halfway into a century last year.
