You have to do a demo with Agrows. Anything grows is nice, however, it's not the same from my experience as the dynamics in the packages mentioned.You can make static fur(or animate), but it won't react properly. The particle system has been improved and allows for some nice affects. For clothing and hair dynamics most use poser as stated, however, Blender, which is free just got some very interesting dynamics that are worth a look also.There has been success importing these. I would expect C6 to see improvements here.Carrara also has good file support as well as great rendering.Carrara is just a little quirky in the workflow area, but it's not a big issue.

No need to think outside the box....
