Plotts?

I don't understand all the talk of plotts being trail barkers I have one that is just over a year and a half old and she is silent and just now figuring out how to trail a hog off and she will out smell my cur dogs any day of the week and I don't consider my cur dogs junk either they will stay with a hog for several hours.My uncle used to run running walkers and I have seen them trail a hog for hours before they ever looked at him the first time and then break bay and run for hours and they were all silent so I honestly think if a person has never hunted behind a good set of hound they don't know what there missing.
