optimize STP with Cat2950 and gigastacks

Hello out there

I have 4 x Cat2950-24-EMI (in a life environment) cascaded with gigastacks
and the both end Cat2950 have normal GE Uplinks the to 2 4506 Catalyst. Both
4506 have a trunk between them. All links are dot1q trunks.

4506----------------GE-----------------------------4506
| |
GE GE
| |
2950--Gigastack--2950--Gigastack--2950--Gigastack--2950
|______________________Gigastack_____________________|

At the moment I use on both 4506 backbonefast, one 4506 is the STP root an
the other 4506 the second root.
and on all gigastacks interface "spanning-tree stack-port" and the global cmd
uplinkfast.

Are there other good option for faster convergence (rapid stp?) if a link
failure or a box failure?
Unfortunately I can't test there...

Thanks very much for supporting

Oliver
