I vorlauf not so much to reduce the bits and pieces of grain in the wort, but to get a less cloudy runoff (maybe some think of it as the same thing . . I dunno) Anyway, the REAL easy vorlauf method is using the good ol' March pump to do the work and not have to drain and pour, drain and pour, drain and pour. Usually by the time I send the wort to the BK, the wort is free of debris and pretty darn clear.
