WW is way way better, not to knock Marks software, he makes some great stuff, but WW is awesome....i'll give you an example, i have a ninja set for M3, pants, jacket and hood, i ran all 3 through WW and converted them to David, doing the conversion is easy, nothing to it BUT i then went to bed and in the morning thought i'd convert to a few others, WW remembers the settings and in about 20 minutes i'd converted the sets to SP3, V3, Freak, Aiko, Hiro and the girl....Steve
