On the Handley Page Victor there was no reverse thrust, only a brake chute. If you didn't want to stream the chute the procedure was to land and wait and wait as the aeroplane very slowly reduced speed to VMBE, then brake as normal. The Vulcan used aerodynamic braking. On a modern aircraft I would suggest full reverse and continuous braking from VMBE down. In the cargo fire scenario would you have time to calculate VMBE?
