flex links instead of stp for connecting other vendor switches ?

Why do you think STP wont work? The only reason is that MST (IEEE standard STP) has some incomapatiblity with the PVST+, but if the Switches running RSTP then it would absolutely work fine.
Cisco has developed the way MST interact with PVST+, you can either:
1) run pre-standard MST on Nortel with PVST+ Cisco bridges and have the loadbalancing in place.
2) run standard PVST+ but this disables the loadbalancing scheme.
If you choose (Flex-Link), then its pretty straight foreward, all you have to do is to designate a port as uplink primary while deignat another uplink to be as backup. You will need to activate also preemtion On the main port. with Flex-link you cant loadbalance unfortunately cause one of the port has to be in Standby mode. Unlike STP..
