Steve, email sent :) I have been playing with this myself and tried to take it back into the setup room and Yscale the bones for the thighs and shins, this seemed to make the flipper and knee spike anomilies go away. This is what I am up to, I don't know much about adjusting the joints for clothing or really how much to yscale the bones, just pushing dials here, but this is a bit better. I hope I am on the right track.
