I actually hit Spirits Within straight after my Shield Lob (or after the first Fast Blade depending on how quickly I reach the boss on the pull relative to the GCD from the Shield Lob). Although it's happening before the Fight or Flight, it has a 30 second CD and thus WILL be up again in time to get the -second- Spirits Within buffed by the Fight or Flight before it runs out.

Using Spirits so early on the pull also gives a little bit more security in the event of a blackmage or dragoon opening critfest, and being used at the start means you should still be full health for max Spirits damage as you'll have the Stoneskin/Adlo from the prepull still on you.
