Is the trinity quieter than the hybrid? The loudest thing on my bow by far is the hybrid. It does not come in contact with anything when it drops but the stop on the inside that keeps it from hitting the riser is extremely loud. You can try it out just by barley pulling it up with your finger and letting it go. Is there a way to make it silent? If not is there a quieter rest?
Try putting some felt or moleskin on it. See if that helps. I did that to one of mine. Don't know if it really needed it because Primes have a distinct sound. I could have been something else.
