Jessi is a real dog when it comes to bending. And the mapping is SO bad. And her eye centers are screwed up, so unless you are keen on editing the jp's, she can't look sideways without them popping out. Also, her head is proportionally wrong in so many ways. At least with V3 and S3, they can share mapping and their bending is way better. That said, Jim Burton has created a beautiful version of Jessi that fixes the bending issue. I for one am looking forward to her. If you're interested, there are threads posted at Poser Pros.
