RE: The quietest bow possible?
I really don't know where the idea comes from that a longbow or recurve is quieter than these new compounds.Every longbow or recurve that I ever shot or heard was extremely loud compaired to these new bows out today.The traditional equipment is using 600-700 gr arrows and still have a loud twang.So you put rubber bumpers on the string to stop that,along with string silencers.Sounds like the new Icon or Legacy.
Now I'm not against traditional and do it myself from time to time but they are not that quiet.
If you want the quietest setup,the Legacy is a good start.A Muzzy ZE might be a bit quieter.Also,bumping the arrow weight up will help.
Really I think you are getting too obsessed and would venture to say that the bow is extremely quiet as is.
Although I personally hate the feel of the Legacy,I will admit it is quiet.So is my Ultratec and most of the upper end compounds out today.
