From my experience, tell your players to make ample use of Momentum. While they're capped at 6, they're relatively easy to generate an really help out. I know with things like Inspiration or Bennies ir Fate Points there's an instinct to treat them like a precious resource. Not in STA. Burn through them! Use them often.
To you as GM... also make use of your Threat. They are Momentum for your NPCs and even the story itself. Spend them often!
