Brace height would be around 8 1/2" - 9" for your bow, JCN. I'd suggest findingthe optimum brace height -for that particular bow, for the arrows you intend to shootand your shooting form - by starting out at 8" and then start twisting the string up until the bow quiets down and shoots straight.

It's better to tune the noise out than try to cover it up.String silencers are for whatever noise that simply won't tune out.
