Arrow weight/ Quietness of set up

At what arrow weight do you notice your bow quiets down? I was shooting 416gr at #65 and have jumped to 497gr and have noticed a good difference.

Agenda 6
28" #65

I don't know what the line is at...I shoot 570gr and the bows are very quiet..

I hear ya. I had thought about adding some 50gr inserts. I gained a lot of speed when I switched bows. All I'm thinkin is that means I can throw more weight at the same speed. Haha

That Agenda 6 should be a very quiet bow already. My favorite bow on the planet behind the arena.

It's definitely quieter than the other bows I had. I like it.
