Just because the base figures, V3,M3,V4 etc, aren't weight mapped doesn't mean that you can't use weight mapping on the clothing. In fact I've found weight mapping can be used effectively to get better movement when used with older gen figues. See the skirt with my "Vintage Pop" for GND 4, in the marketplace as an example. The only drawback is they can only work in Poser 9 or PP 2012. If you own eitherof those programs and are creating just for yourself then why not use the rigging that gives the best results for you purpose?
