I've often thought that dogs from working lines should have their working styles listed as well as their names and titles. Champion lines would mean that there are champions in the pedigree somewhere. It does not guarantee that the pup will become a champion or be of championship quality. It can mean if you buy a show potential pup of this type of pedigree, that there may be higher odds that the pup will do well, because several generations have done well. It does not guarantee the pup will work or even be of a quality to work well.
Same rules apply here as to the champion section.
It's best if you can see a number of the breeder's animals working on stock to evaluate style and working temperament. One more thought on the buzz word type of person. Just recently it was called to my attention that some breeders of working dogs are advertising working titles that they themselves award at their own sponsored trials.
