I didn't dare to install RSTP (or MST in Cisco terminology) in my backbone for three reasons:
1) it's too fresh and I'm afraid of bugs
2) if you're running it along with PVST+ switches (and you have to because Cat3500 don't support MST, e.g.) you must move the root bridge into the MST cloud - it's impossible to leave the current network as it is and just add new MST switches
3) from the PVST+ switches point of view the whole MST cloud looks like one "big bridge" which can make STP troubleshooting pretty complicated.
Generally I would try it in a case of building a new network but not in my living productive network which has to be up and running 99,999% of the time.
