CX-70 and Campy Centaur CT: https://flic.kr/s/aHsk1iQ4KS
For what it's worth, I moved to a 42/28 setup on the cranks now, and I'm putting another CX-70 on it. Will test this out to see if it was the original 44 ring, or the 14-tooth shift that stressed the derailleur. I have a nice Suntour XC Pro FD on my other bike with the Herse cranks (also 44/28). No problems ever. Love that stuff - almost bought some NOS Suntours a while back. Gevenalle looks promising, too: http://www.gevenalle.com/store/products/derailleurs/ Supposedly stiffer steel cage (to handle demands of mud-caked CX races), and not badly priced.
