In keeping with understanding the fretboard and juicing every bit of the pentatonic scales,its very important that you learn them in all positions all over the fretboard and learn how they work over different chords. Also when you play a scale with 3 notes per string try leaving out the note in between the two extreme notes on a string giving you a wider intervallic sound. This will change the way you perceive the scale and change the way you sound using the scales you are familiar with. The great teacher Don Mock had compiled a white paper on pentatonics and its here for your perusal.Any scale must be understood and its application maximized to truly progress,this is true with anything.
