Anything you guys put on your string will do three things, lol. [1] cost you some fps [2]change your pont of impact [3] fly off sooner or later. At the risk of sounding like a smart arse, the only thing you can do is buy a set of ear plugs. I'm sure some of the other xbowers will tell you pretty much the same thing. The deer are dying when they hear it, if you do your part right. Both your bows come w/ dissapator pads, that's what Excal came up w/ to quiet them, if there was more available they would provide it.

As to the moon nocks, you can use them, or grind the ends flat. If you do use them and position an arrow wrong you will get either a total or partial dry-fire and it's inherent thrills. I've ground a bunch of them flat for other friends, but was a machinist for quite a spell. Have fun!! Congrats on some great bows too, btw.
