What arrow? What fletching?
I have been using Easton ACC's and Blazers through a WB on a very quiet Mathews HTR with hardly any sound other than the arrow hitting the target.
He is using 31" 2314 with 5" plastic vanes right helical @ 65lbs on a round wheel cams, martin cougar magnum, teardrop cables and dacron string.
Its a older bow that is in good shape and will get the job done if he does his part.
Thanks for that additional info! There can be issues with aluminium arrows making noise against the WB during draw and upon release. If the WB is of a newer style, with the black strong bristles at the 6 o'clock position for support it tends to be quieter.
I'd recommend a light wipe of Armor-All on the shafts and let dry. That may give a little lubrication to help with making the system quieter. No knocking his setup, but it is far from being as quiet as more modern bows. Even that arrow and vane set up will be noisy compared to a carbon shaft with smaller vanes like Blazers.
Make sure the cock vane is not traveling through the black bristles at the 6 o'clock support position.
Yep, it will do the trick but it will be impossible to get it super quiet. But the trade-off on how reliable a WB is makes it well worth it especially to a more novice bowhunter!
Fingers or release? If shooting with a release, and draw length allows go with a release loop on the string. Helps centershot and can quiet the shot. Fingers can open a whole other can of worms regarding arrow not staying on the rest.
