That's a valid request, and not that I can answer it as I have no experience with the Sport gear. But from what I've read, it was a poor performer mainly due to having only one jockey wheel. Others can add better detail, I'm sure. A lot about the various performance attributes of rear derailleurs can be learned by reading Frank Berto's excellent book The Dancing Chain. Well worth the investment.
