Over the years have made hundreds of patch cables using this stuff and it certainly works great.
Fits all industry standard XLR and Jack connectors (Neutrik's, that is to say) just fine. All materials used in this cable are excellent and very nice to work with. With proper sharp hand tools it's really easy to build cables using this product as the base conductor.
Stays flexible and thus has a operational long life regardless if used indoors or outdoors. Also suitable for winter outdoor applications. Becomes a bit rigid when exposed to temperatures far below zero but works nevertheless (and doesn't lose it's flexibility for good).
For analog patch cables I wouldn't settle for less. Well made, sturdy and doesn't cost a fortune.
