Which Smart - Opener Workout to use as pre-race warm up?

I’m going to race a crit. Is it better to use Smart - Opener 2 Workout to warm up? Anyone got experience?

In general, you want short, race-like efforts as part of your opener. Don’t get too tired (too much XSS) is the only rule you should pay close attention to.
