The brace will decrease if you up the poundage, and im sure other small stuff will as well. Idk how much difference in the tune it will make???

Btw, my 101st was quieter at 53#'s thenit was at 61#'s. i was shooting a close to ibo arrow at 61#'s so that was probably why but... If you are using the same arrow, then your bow will get louder not quieter b/c your speed will increase.
