When I started using Poser, V4 (a Daz product) was the go to model. The incompatibility came later. I just now bought Poser Pro 11 and am downloading it now. I did get La Femme to open in Daz and was able to do a lot with her but there are so many problems. Even with limited functionality, she is a great model. I'm looking forward to seeing what Poser Pro 11 can do.
