/shrug -- just relaying the post since my search-fu is stronger than most people's.
I don't think there is a "perfect" hand position, and that's why too much padding can be a bad thing. It interferes with the sensory feedback loop between your hands and your brain, and encourages you to leave your hands in any position for too long. The trick (in my experience) is to keep your elbows loose and move your hands around frequently.
