Between @@Corto and myself I'm confident we can answer anything you can throw at us. I may have built that rig but he was the one who taught me Softimage years back, we definitely have a lot of experience under our belts in this area. Also make sure you have the most recent version, I'm always updating that rig to make it better as I learn more and more, there's so much you can do with a program like Softimage, especially in it's very finest mode and what it's know best for which is animation. Just seeing what you can do with such a simple and very limited program like Dragon I know with a real animation package you'll be able to make some amazing things and not just that, you'll do it in a fraction of the time because you'll have an IK biped.
