Can you recommend me a hair model, that can be decimated ?

Hey guys,
I came to the conclusion that not every hair can be used with the Decimator tool. For example one hair can be 300k polys and you can reduce it down to 150k and it will look aweful, while other hair model can be 300k and can be easily reduced down to 4k without that much of a quality loss. So it's just "luck" whether it will work or not.
Let me know if you have tested some of the hair models and the quality remains almost the same after the poly count is reduced. My target is around 20k, but even that is a lot for just a hair model.
