Thanks for the input, folks! I really appreciate it. I will definitely stick to it and give these pedals a go. I really want them to work for me so I will keep at it. It's comforting to know that others have been there, done that, and got through the tough initial stages!

Cruziegirl, thanks for reminding me about cafe covers. I have them for my X-2 pedals, but they won't fit the Zeros. I'll pick some up very soon - you're right that they are a must for keeping crap out of the pedals!

Thanks again....Emily
