A210: Rarely. Swordsage recovery mechanic is totally worthless. You should split your maneuvers into about half strikes and half boosts/counters and just deal with using each of them once per encounter. There's a feat that allows you to recover all your maneuvers (from all classes) as a full-round action, and picking it up (and multiclassing) are generally mandatory for top-tier Swordsage builds, more because it helps out in the event of shit hitting the proverbial fan and you finding yourself without maneuvers.
