Well, moving around in scales is all about changing the intervals... You have to be creative, and let lose and be a "little" random about the notes you choose... Though you need to keep a train of thought behind it... The more you try, the easier, funner, and satisfying it'll be. Well, Pentatonics, minor or whatever, can sometimes make lead runs sound a bit "dry", so keep in mind what kind of music your playing.... Predominanty, I've seen Pent.'s used in Rockabilly songs, like Stevie Ray Vaguhn's music... What you can try doing is modulating from the Minor Pent. scale to the blues, as I figure the Pent. Scale is really rhe "frame" of the minor scale. Besides, the Blues scale is derived from the minor scale, and can make a lead run sound great behind m, m7's, 7's, and so on, chords.... Experiment, experiment, experiment... Hope that helps.

PLUS!

Incoperate your personality and mood into it. This may be hard, because at first your still trying to make things sound good. Again, keep trying...
