When I shot a recurve I used brush buttons. I also put stick onfelt/fleece and stuck it on where the string grooves are which stopped any noise from the string hitting the limbs. I also used cat wiskers I found around 10" from the limbs tips was the most effective for my recurve. Now with my longbow all I use is cat wiskers. with all these items If it did slow my arrow down I didn't notice. I would rather have a slow quiet bow than a fast loud one.
