Rick;

MeanV2 (his handle on archerytalk, just like mine is swampcollie and yours is rickmur) makes these string suppressors/string stoppers. Just like that carbon rod you see on Ross Cardiacs and the new Hoyts, and the STS which has been around for a while. MeanV just gives it a nice clean look, adds a bow jax and will make it EXACTLY to your measurement specifications. All he needs is the measurement from the bushing on the back end of the stabilizer hole on your bow, to the inside of the string. His CSS (Custom String Suppressor) sells in black for $34 TYD and in camo (pattern of your choosing) for $44 TYD. Turnaround time is about 3 weeks normally, but I got mine in about 2.

As you can see from his thread, which is now on page 44 at 40 posts per page...they are pretty popular.

Here's a picture of the one he made for me on my HCA Iron Mace.
