So could I go with a Shimano XT Shadow derailleur?
You can use a 9 speed XT Shadow rear derailleur, but not the newer 10 speed Dynasis type. The 9 speed is compatible with Shimano 10 speed road shifters, the 10 speed Mtn stuff from Shimano uses a different pull ratio and requires 10 speed Mtn shifters.
