Masterline Optimiser Jump Line The Masterline Optimiser Jump Line is a core-rope tournament water ski jump mainline — a rope inside a rope — built from PolyProMAX yarn. The dual-rope construction is smaller in diameter and more aerodynamic than a single-line jump mainline, so the rope cuts through the air with less drag through the cut and approach. PolyProMAX is selected for its snap-back behaviour under load — the same yarn family Masterline uses across its tournament jump lines. The Optimiser sits in the lineup between the standard Kruger Jump Line and the Kruger Pro for skiers who want the aerodynamic edge of core-rope construction without going to the Spectra Fusion of the Kruger Pro. Choose the Optimiser Jump Line if you're tournament jumping and want the aerodynamic advantage of a thinner core-rope mainline.
