Also magnets cut down on file sizes. Volup Vicky 3 uses magnets and I've managed to get nearly the same shape using those as I have with my v2 figure and nearly the same file size. Plus magnets allow you to form the clothes to the shape in most cases. This way you don't need MTs at all except maybe expression MTs. But the making of a single MT for each part then stripping out of all other MTs is the other way to go. My v2 figures have just one FBM for their shape.
