what is a good and simple chord progression for harmonic minor practicing?

what are the best chords to use? (i.e. minor, major, minor 7ths, major 7ths, etc.)

i want to start expanding my soloing capabilities

"Musician Talk forum" will give you much better explanations. They are very helpful there.
listen to Opeth. they use harmonic minor all the time. A fair Judgement is particularly evident.
