Once I started using the Kanati Pro Angle bow quivers, my others fell by the wayside. They are a GREAT bow quiver. Solid, silent, and they look good. Super quality also.
You may want to do a search on bowstrings for your Widow. I was a proponant of after market strings until I read Ken Beck's piece on their Black Widow strings. He tested them against some of the best, including skinny strings and they (the B.W. strings) proved to the the fastest (aside from one a.m. string that beat it by 1 fps.) and the quietist on the B.W. bows.
I have tried many types of silencers on my Widows, but with my 32.25" draw, the rubber spider legs have proved to be the best for my application.
Good luck and congrats on a fine bow.
