When I started bowhunting, 38 years ago, I used a Bear Griz, and wood arrows, and had deer jump string. Before my last shoulder surgery, I was shooting a Matthews Q2, and had deer jump string, with straight fletched vanes. Now after the surgery, I'm gonna shoot parabolic, slight helical, and aim for lower third. It's worked thus far. I think bow noise, is far more important than fletch noise. Arrow material being second. Aluminum arrows make a metallic sound, carbons seem to make more noise than cedar. Just my experience, which means little to anyone but me. Good luck, but arrow noise, is the least of my worries. Just my 2 cts.
