A few things I would do first:
1. Dump the widow spiders, they've never worked on any BW I've shot or owned.
2. Remove your string from the bow, lay it flat and measure the length, end of loop to end of loop.
3. Divide that length by 4.
4. Measure that distance from the end of the loops down the string and mark that spot with a Sharpie pen. This is where you will place the silencers.
5. Purchase a few sets of silencers from Bow Hush and install them where you've marked the string.
This and a heavy arrow will get you a long way down the quiet bow road.
My .02 worth,
