As I mentioned in the "Dominant Species" the minor 7th chord is sometimes better approached through its relationship to the major scale. In (a), I use the F major scale over three progressions that are commonly found in jazz. In (b), I show how you can interpret the II of the II-V progression as being a voicing for a I major chord, and stick with the same scale choice over the V chord to hit the extensions, until you reach the 3rd of the V chord. Experiment with these possibilities in the context of tunes.
