On my Scale I ride the Ritchey WCS spd's, they do very wel. Do not use the cheaper Ritcheys they do sh#@ with me after several 100 miles.
I picked up some cheaper Ritchey V4, and tried them. I liked them, maybe better when broken in. So far only one time got stuck, but chalk it up to being new.
Those eggbeaters were the smarties by the way.
