My recollection, what I was told back then was, that the regina chain was stiffer and the campy derailluers seemed to need that. The Sedis would shift really well for little while (at first maybe better than the Regina) but quickly loosen up and get pretty sloppy. It didn't seem to stretch any faster or wear out quicker, it just got kinda flexy. This didn't seem to be a problem with other derailleurs.
Or this could be the stuff they told me to shut me up and send me back down to the basement..................
