Twist rate (twists per unit length) can also have a significant impact on string performance. Too few twists often makes for a noisier, harder to tune string, because any slight strand tension variability is amplified, and the string has less “give” to help with reducing noise and vibration after the shot.
On the other hand, too many twists may reduce performance and may lead to a string which is more prone to stretching with use. With that said, strings can work well with a fairly wide range of twists, for example for a 68” string, anywhere from 20-60 twists will produce acceptable results as long as the bow’s brace height (string height) and correct. Generally more twists will slow the bow slightly and produce much less noise, while fewer twists will add a tiny bit of speed, but potentially more noise.
