Problem render fibers in Best Render

Hi all!
I have a problem with rendering this very nice fibers!

If I render the fibers with BPR I get very nice hair.

If I render with “Best render” the fibers looks like under the fast preview! Where is my false?

I try turn on the “Render Fiber” and the “Antialiase Fiber” option under the render tab, but nothing bring better results.
