Sorry for all of the questions lately but being new to bow hunting I'm trying to learn some things. I have a pack of string dampeners and string whiskers. Can I put both of them on or just one of them? If just one , which one would you suggest and how far down do I need to put it on each end. If I can use both , where should I put them? How much speed while I lose? Also the string dampeners, it says to crimp the first band to the string, then fold the silencer and crimp the other 2 bands around it. Does the first band need to be crimped snug on the sting? I'm worried that it could damage the string. Thanks.
