All like string stops, and most seem to think they make a huge difference. I guess it must be the bow its on. I don't dislike string stoppers, but I really did not see that much of a difference. I used an original STS with a Darton Tundra. Dartons are known for vibration, and the STS did eliminate that. Noise? It changed an "ong" sound to a "whap." It seemed to me to be just as loud, but sharper. Since they came about when parallel limb bows became popular, I'd have to assume they do a good job with noise and vibe on a parallel limb bow. On the Darton, it made the bow no quieter, and on a Pearson, mine actually made the sound louder. As far as shooting consistency, that is still 98% shooter. Again, I don't dislike them, but I would not say they are needed. With cat whiskers on the string, a bow can be plenty quiet without a string stopper. JMHO
