The null figure method is better for combatting cross-talk than the method sustained by Ron (aka crisjon1950), and there is still another method proposed by Bloodsong, but you can check the FAQ for the basic info and try all methods to see which works best for you. I think that rbtwhiz created the null figure and it is posted at DAZ, where you got Vicky. They should have some information about it too. There was a tutorial at one time. When these figures first came out everyone had problems and there was a lot of discussion.
