I've held puppies too, and very few screamed loudly and endlessly. Most made panicked squeaking sounds, but once put down with its littermates, they got quiet again. We actually got to where we would hold one a certain way (special hold with the puppy rear-facing) while having a second puppy blocked in our arms (hard to explain, but puppy was safely and securely on a thick towel on the table awaiting it's turn). The puppy being docked was able to smell/touch it's litter mate, and the noise made went way down. I'm not going to argue what occurs (the tail is cut off at a specific vertebrae depending on breed standard), but I'm not going to say the puppies screamed for hours. It is what it is. I couldn't tell you the number of tail docks and dew claw removals I assisted in, but my next dog is going to be a Rottweiler and she will have a docked tail. As for tail docks and ear crops, they are more different than they are the same. Both are cosmetic procedures for the most part, but some working dogs have it all done for working purposes. But one is done between 2 and 4 days with no anesthesia other than a little numbing cream, and the other is a major surgery done under general anesthesia preferably between 10 weeks and 16 weeks of age. As for the original post, as Fran said, it's about determining what you'd give on and what you wouldn't. Personally, I'd take a docked tail over no health testing or titling or what have you.
