The stringsaver saddles are absolutely fantastic! I fitted these to a Mexican Stratocaster kept breaking guitar strings. The guitar also suffered from a very poor sustain. Fitting stringsavers was a doddle, they were a direct replacement for the other saddles and they didn't take up any more room. The smoothness and quality of the saddles is second to none. They do ruin the vintage look of your guitar so I wouldn't recommend them for a custom shop guitar however, for the Mexican Stratocaster I fitted them to, I feel they enhance the look. They also reduce the amount of scratching on my palm from the standard saddles. If you prefer a more classic look I believe Graph tech offer a stainless steel saddle with a String-Saver insert this may offer you the best of both worlds.
