is there a difference between cord sold as "accessory cord" and cord sold as "cordalette?" is one more specifically geared towards anchors? ie low-stretch, static etc. is static preferable for building a study anchor on a wall?

hope everyone had a great halloween [-_-]

7mm perlon that is sold as accessory cord does the job nicely and is one of the less expensive options. This is also I believe what John Long recommend in his lastest anchor book. my $0.02

sometimes- Sterling and Mammut both sell a type of accessory cord that comes prepacked and is somewhat stronger and more abrasian resistant than normal perlon.

Other companies, like Bluewater, are just selling pre-cut accessory cord.

Both types are effectively static and are more than suitable for anchor building.
