The grasp and thumb grasp dials are pretty much useless as far as I'm concerned. For my rapier poses, I've had to do each joint of each digit individually and I still run into a basic flaw of Poser. Flex your palm--no, not your FINGERS--flex your PALM while keeping your fingers STRAIGHT! Yes, normal human beings can do that, and it makes up a VERY important part of the grip, but the way the joints are set up, the Poser palm stays rigid at all times with no flex.
