The VP100 should cure the problem of the lobing you are getting and the difference in SQ is very minimal, the VP150 is a little pickier for placement.

You could also try aiming the VP150 at different levels, higher or lower than seated listening point, to see if one spot helps eliminate the hollow effect. I have mine angled slightly upward and it actually points past my seated hearing position and sounds pretty good to me.
