DAZ is no longer just a content maker. They now make D|S, too. And that may just provide the posing solution you want. D|S is supposed have a more sophisticated rigging system than Poser. I think their next version of Victoria may have a D|S version that takes advantage of the more advanced rigging.

Poser 7 may also have an all-new rigging system. That was hinted at. Supposedly, the new rigging system will make buttocks and divided chests unnecessary - hence Jessi's Posette-like joints.

They are fixing Jessi's hands and feet. I doubt they'll fix the rest of her, unless villagers start storming the castle with pitchforks and torches. Changing her joints means her clothes won't fit. Not just the CL-made stuff, but all the merchant-created things.

If Jessi is re-rigged, I think it will be by third parties. Perhaps Yamato will make a TenTen Jessi?

I don't think Judy is the best female body. She's the most realistic, though. Not anime-ish like Jessi, not idealized like V3. More of a real woman. She doesn't pose or morph all that well, though.

And what about low-res Jessi? To my eye, she looks just as good as high-res Jessi. She's got the same number of polys as V2, so is much lighter on the system resources than high-res Jess.
