I have shot predator bows for ten years now, and found that padding the string loops, and just about any of the common string silencers to be more than adequate to quiet them down. I will add that I`m very picky, and my bow MUST shoot quietly. Bow hush products are very good, and in a short time they have developed a big following for good reason.
I make my own strings, and made a few dacron strings to try out. The newer string materials are much more durable, and stretch much less. Dacron will work, but I much prefer D-97.
Never tried limbsavers. I`m sure if you are still getting more noise than you care for, that these would help.
I keep my arrow weight up to and slightly over ten grains per pound. My bow produces a deadly, silent "thump" at release, and there is no reason your bow won`t do the same.
My Predator(s) make me look like a better shooter than I really am. If that bow comes to fit your style like mine does me, you will not believe how deadly you will be while hunting.
Congratulations on your purchase. It`s a beauty!
