In your testing, put a 3rd switch in place with LACP and one leg to each member. My testing (45/42xx) has shown L2 should be pretty much hitless under most circumstances (except if your STP topology needs to re-converge), and L3 should around the 1-4 seconds mark (for violent failures of master RE). The worst case scenario though is re-merging a split VC, which can take the best part of 45 seconds, so avoid split-brain scenarios whenever possible with redundant VCP/VCPe or schedule their repair during planned outage windows.
