if track speed can be an advantage ....... why not silent

why can't silent be an advantage also
Oh I agree Mr. Larry., one of the best dogs I ever seen hunt was one of urs,, she was 4 yrs old and was hunting that morning with my old male and my parker males daddy. All three dogs were silent on track and still ran that boar hog for almost 4 hrs,, bayed him 3 different times,, CD went in on the last bay about 40 yards from us and when he caught the boar hog raked him off when he left out... We talkin 350 pds of pure Russian,,, he prob had been caught before and he wasn't no rookie.. But ,, like said before,, if they gonna run it don't matter if the dogs barkin behind him or not.. Some is just smarter than others to me..
