Interesting! So, to see if I understand correctly, what you are saying 
is that you /only/ use the guide hairs from Poser and 
generate/extrapolate the hairdo from there? No need to use the fully 
populated Poser hair? That is a great approach and probably faster than 
generating sphere_sweeps from /all/ the individual Poser hairs, which 
was the thought I was following until now. Well done!
