Vray3.0 Fur As Lawn Grass

Vray Fur as lawn grass test. I have a noise map in the length slot, grass texture map applied to the Vray Fur Object and a different and darker texture applied to the ground plane.  Also, the tessellation on the ground plane is about 3" x 3" quads.  This increases render speeds for dense grass. My per area distribution number is 500.00 and the frame rendered in between 5 and 6 minutes.
