I remember 20 years ago I had one of those Bear hair rests. Never ever remember it making noise when drawing for target shooting. I was using aluminum arrows back them. A doe walked past me and I set up, picked my spot and started to draw back. All was very quiet and I remember hearing "Shooo" as the arrow slide across that fake hair. The does ears pointed back too as she heard it. Luckily I released quick and killed her. I continued using the hair rest but switched to wood arrows and they are quiet on the draw.
I have used the elevated rests too, but I have had them break before and ruin shooting until you buy another one.
Personally I would use a hair rest with plate as its simple with less to break. Just relaying my story of the noisy arrow.
