I don't like it as much when the property has good undulation and the native grasses distract from the contour.
Couldn't disagree more with this thought. IMO trees most definitely will do this but not native grasses.
Regardless your flavor, if your going to do it and want good results you need sandy to sandy loam soils that drain well or spend a small fortune sand capping and drainage on heavier soils to produce thinner natives. You have to bleed the fertilizer from years of growing parkland KBG fields, make sure its not getting any irrigation after establisment and hope for warm dry summers to thin out the fescue.
Also, stick to sheeps and hard fescues if you want fescue native, avoid creeping red and chewings. Unfortunately, you really can't get sheeps or hard in sod since it won't hold together very well, which means your looking at a 2 year turn around of seed establishment. If your doing a project and have advance timing you might find someone who will contract grow sheeps and hard with 50% kentucky blue seed in it then once its mature you could kill out the ketucky blue leaving you a thinner stand of sheeps and hard fescue.
