[Rob Katz]"would would i be able to "dial away" the glare w/a 4x4 polarizer filter?"
Probably, if he has been using a polarizing filter with that box... then that particular box probably has a rotating filter stage (many boxes do, although not all matte boxes). Assuming that's the case, you put the filter in the tray, put the tray in the matte box... and rotate the stage at will, just like you did with an on-the-lens circular filter. Much easier, in fact.
