After reading the replies on paterson tanks and reels I have ordered a set up. My question is do these reels require any different agitation techniques than standard stainless reels? I normally agitiate one full minute the first minute and then 5 seconds every 30 seconds there after with a standard inversion and twist method. I get very consistent and even negatives this way. The paterson instructions I have seen seem to indicate a rather different approach of minimal agitation. Is there a difference? RMolson
