Nice day to be back :)
Do you use SPD or Look type?
Luca - not there yet, but they're higher than the last ones.
Deano - speedplays
Thinking of switching from looks to speedplay as it seem its what Pros chose.
@ Deano - That's a sponsorship commitment- not always personal choice. I'm sure your Look pedals are just fine. If you are having problems with your knees, I would look into a bike fit- no need to get new pedals and cleats.
