Campy link in a Shimano Chain
 

I was putting a shimano 10spd. chain back together, and in a pinch I only had a Campy link to push in there, it seemed to work perfectly, no problems getting it in, the width is right and it is smooth running, is this bad? Am I messing with the component gods by mixing? Never read that it doesn't work, but I have never read that it does either.
