The 10 speed Shimano MTB "Dyna-Sys" parts aren't only group-specific, they are incompatible with road indexed shifters. The cable pull is different. Folks on here and elsewhere say to use a 9 speed MTB derailer if you want a 10 speed indexed setup.
I'm using a long cage silver Chorus 10 speed (early '00s) on my Rivendell with an 11-30 9 speed Shimano cassette and Shimano bar end shifters and it's working fine with 46-36-26 chainrings in the front. The Chorus was rated to handle 29, so jumping to 30 doesn't seem like much of a stretch. I've thought about going 11-34 or even 12-36 on the back to try to get me up one particular hill on our local brevets that I have walked every time this year. But I feel this would require a MTB derailer, so I haven't done it yet. The new derailer I really like the looks of is the new Suntour XCE. It's basically a polished silver Microshift and it is pretty. But it comes at a premium, I've seen it online for around $100 whereas the Deore can be had for less than $50. I really want it though so maybe I'll sell some more stuff I'm not using and get it.
