Just a word of advice, the more you discuss your screening methods, the less useful they become. I also wouldn't ask this question openly in a coed area. All businesses/industries have "tricks of the trade" & that information should remain as concealed as possible. I'd never divulge exactly how I screen to the masses. When you do so you are giving people a heads up as to exactly what you are looking for thus allowing them a chance to "fake/create" that information.
