I'm currently trying to train my husband's eye to spot faint lines. Each time I see one on CTP I ask him if he can see anything... why is it women are hawk eye but men are hopeless?! I swear I could walk in with two fat lines drawn on my face and he wouldn't notice lol!
I think, seeing what I can see, I don't see how they could all be wrong unless you have a faulty batch. When are you expecting af to arrive? I know you don't like frer and I know what many say about blue dye, but how about a digital closer to the time you would expect af to show?
