The thing is, the script is SO good, that I can't tell the difference between the fit of the weight-mapped clothing on weight-mapped V4, and that of the non-weight mapped versions.

In general, products created by vendors who've done a really good job making their clothes fit my highly morphed characters in the first place (like 3D-Age, for example), go through the script seamlessly.  It's easy to use and VERY quick!
