Depending on how stiff you want it, maybe even wobble operator can do the trick (for very stiff).
Other then that, you can either use particle physics, or PhysX with very high binding numbers so it's stiff enough.

thanks for the reply. i think we have spoken before!
the problem with hair/fur is that i cannot add a modifier above it.
Have you managed to do something like this before? im really battling. even the autodesk support is not helpful.
