I have a Synergy with a QAD Ultra LD rest. Each shot has a "clack" sound as the rest drops. I thought it was where the rest hit the bow shelf but doubling the amount of moleskin on the shelf does little for the problem. This is not an arrow contact issue. The rest makes the sound when manually actuated also. Any ideas?
Unless you feel comfortable opening up the rest and dealing with all the small internal pieces, I would go to your local shop and have them look at it.
Otherwise shoot an email to the manufacturer and see what they can do.
