What is the model of Shimano 10s road rear derailleur with highest spring tension, that also fits a 11-32 cassette un-officially (with normal, longer non-Campy derailleur hangers)? I am done with SRAM shifters, and want to run 10 speed Shimano road shifters on my cyclocross bike. One of Shimano's neutral support mechanics at an event earlier this year recommended the Ultegra RD-6700. I have also heard that the 105 RD-5701 has a stronger spring than the previous 5700 version. What about Dura-Ace RD-7900?

You can run a 9 speed mountain rear derailleur like the XT M772. There are also ways to increase the spring tension by changing the position of the cage spring but I haven't tried it on any of the recent models.
