I get noise from my feathers on my Axis(very noisy) and FMJ shafts but I don't hear anything from my GT (75/95camo). I thought is was because of the weight difference but they are only 20-30 grns. different(GT's are the heavyest). Maybe it's the shaft dia.

I'm shooting an 07 Allegence 70lbs 29" draw (27" arrow). Maybe the noise has something to do with speed. Not sure how fast my arrows are going, maybe next week I'll crono it with the differnt shafts.

I really like the feathers but the noise bugs me. My Blazers don't make any noise.
