I think silence is nonsence unless there is a stalk going on. I make an effort to me quite but if I make a clank or snap from time to time I don't get bent over it. One noise might not blow the whole deal but repeated sounds surely will. I have made noise on purpose just to see what kind of responce a deer will have. Like clicking my release on and off a few times. Some of the time there will be no responce and other times just an ear rotation. If the deer seemed skittish they just might take off. I certainly don't think a noise will sour the whole day.
