Pierre and SBD Bowstrings has my business for life!
They produce a superb, high quality custom-made product which has exceeded all my expectations for performance, consistency, longevity and craftsmanship. As I replaced the originally provided strings on some notable high-end longbows, there was always a substantial improvement in speed and shoot-ability. In one case, the same bow picked up 8 fps in addition to being noticeably quieter.
Arrow spine needs to marginally increase with the addition of the 6 or 8 strnad strings, but it certainly is worth it.
SBD stands behind their product completely, and their customer service is second to none. Pierre and family are kind and dedicated craftsmen and the kind of people I want to support. This is why I say that their strings are now on, and will remain on, every bow I own.
