One thing to remember is that most Poser characters are meant to wear clothing at one point, Vicky eventually leaves the temple you know! So whatever fancy joint controlled morphs etc... you devise to get rid of those shoulders and other pesky problem areas, have to be duplicated in the clothing. That's one of the reasons why it's best to limit those joint controlled morphs, they are real hard to duplicate in clothing. Rigging is an artform, it does not matter how high end the software, all rigs have to be tweaked and finessed. It is not uncommon in production to have 3 or 4 rigs for the same character to be applied in different circumstances.
