I'm not sure what the benefits are of the new Victoria 4.1.  It now contains an external morph injection system similar to what was used in V3.  I seriiously doubt that anyone other than DAZ will use this new facility.  The original V4 still has 50 or so extra morph channels built in that people can use.  Also, I wished they would have fixed her armpit joints in 4.1.  Personally, I see no need to use 4.1 -- it appears that it's more hassle versus benefit.
