The long draw length and 3 under will make about any bow loud. I struggle with a 32.5" draw and found that two sets of rubber spider leg silencers seem to work best, along with velcro pads at the string/limb contact points. I also wrap (pad) my string ends where they contact the limb grooves with yarn. Helps a lot. I found with my bows and draw length, the original Widow strings were quieter than the SBD strings. I had no good results with puffs, Hush, etc. Rubber silencers did better for me.
I shoot my Widows at the max (9") brace and it does the most for quieting the bows... so much so that if I have a new string, I can hear when it initially stretches and the bow becomes louder until I shorten up the string to reach the 8 7/8" - 9" brace.
I have read that if you take them apart often, that the little "O" rings on the limb alignment pins get squashed flat and can cause noise. Folks claim if you put new ones on that it will help with noise.
