Quote - .... Make your styling in the modeler,  export,  change ALL instances of the letter "f" back to "l" (again depending on your modeler) , then re-insert the new hair object data back into the ".hr2" file - being carefull to observe the indentation ( find&replace can help you there as well.)  (I suppose a Python script could be writen to help automate the back and forth. )

It's quite do-able, and with some practice you should be able to make stuff never seen before.

(see images) 

I've been toying around with the idea in Hexagon of creating dynamic hair.  It will model lines and you can import those lines into Poser.  But, I'm not sure how to get them declared as "dynamic hair" objects or recognized as such.  That would seem propriety to Poser, wouldn't it?  So, it may take more trouble than it is worth to model dynamic hair from scratch outside of Poser and then import it.

But, as far as styling goes, if you can preserve all the necessary info (if there is anything other than the model itself) your method sounds like a way to do it.  I'll have to try that and see.
