Double Braided Working Ropes
Double braided lines are just that - a rope inside a rope. The core and cover are balanced and share the load almost equally. For this reason, the are not recommended for natural-crotch rigging, because the friction of the cover with the tree causes and imbalance in the load taken by the core and cover braids. It is an exceptionally strong and low-stretch line but should be run over smooth sheaves or bollards only.
