I use the Wippermann 1008 (the less expensive one) on my Campy Record 10 speed UD rear cassette and have had absolutely no problems with it. Easy as heck to get off and clean too becuase of the Connex connector. Last year I even found them on sale for quite a bit less than mentioned above. They also make a stainless steel one and I think the Ti will also work (asuming you want to spend almost 300 beans for a chain)

edit I just googled around and they are on sale again. Lickbike.com
