i think they are mostly pointless for print film unless you are talking tungsten vs daylight exposures, and even then, a decent lab should be able to correct away most of the difference. if all you are talking about are 81 filters, there isn't any point. maybe if you used 85 filters all the time, but even then i think it is marginal usefulness.
