Both the game master and the Dorado can be made almost as silent as the best longbows.
String slap on the limbs is not going to be as loud as you may think.
The loudest part of my shot from my dorado was the string hitting my old arm guard.
I got rid of that arm guard an now she's a silent killing machine.
This is my own set up,,fast flight flemish string,brace hight 7 3/4,any good string silencer,,I've used heaps of different ones an they all work on a correctly tuned bow,Thread tape on the limb bolts,those bolts have a very course thread an they screw into an alloy riser,a sure recipie for noise,a thin strip of wet suit material or felt over each string grove,felt on the limb bases between the limb an riser.
I also shoot with a short reflex rubber type stabiliser when I hunt with it,but that's only to off set the wheight of the Hoyt 4 arrow quiver,,it helps a little with vibration and noise,but not that much.
The key things are the thread tape on the bolts,the felt between riser an limb base,the felt or rubber on the string grooves,and any old string silencer.
A tip about string silencers,,they only take the vibe's out of the string,,they do nothing else.
