I'd say there is a time for both. Just before the rut,I make some noise. Never saw a decent buck run from a fight. He may not close in,but they are not scared of it.
I rattled a doe with triplets in Sat nite. Let her go on by at 6 yds,15 min later a good buck chased her 80 yds out into a crp field. I then rattled/grunted(nothin too crazy,just rattled the rattlebag once and grunted twice). He strutted in to 17 yds and I mmmmissedd
I will never make a noise to stop one again,their reflexes are instant!!! If he don't stop,he will walk on from now on.....
