I often use dynamic hair, even as far back as in 2004:

One of my own attempts (nudity):

There's been a change in the rendering of dynamic hair, the later Poser versions require a lot more hair density.

Using a low poly proxy as a collision object helps a lot with dynamics calculations. kirwyn had some hair collision proxies for V2-4 and Jessie. I use them quite a lot, calculations are fast (often 2-3 per second on an i7)

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
