 - Higher strength – higher working factors or reduced number of working rope falls
- Robust Construction, containing large outer wires to withstand wear
- High surface area – resistance to abrasion and reduced sheave wear. Also improved spooling on the Drawworks
- Added strand support, provided by the bristar core
- Increased fatigue properties
- Resistance to crushing, on the Draw works
- Effective Diameter control, permitting working to much tighter tolerances in sheaves and Drawworks grooves
