Yikes! It really depends on the charater you're making. A snake can have a lot of joints, but a robot very few. For an animal or human type figure, I wouldn't go much more than the number with Mike of V2. Although I would like to see a character with a more flexable backbone (like a cat). I personally prefer using joints for posing rather than morphs, so I'd opt for more joints and less morphs whenever possible.
