OPST Oval Line – Mono Running Line with Enhanced Performance
Tangle-Free. Twist-Resistant. Smooth Shooting Mono Line.
The evolution of mono running lines is here. Introducing the OPST Oval Line — a next-generation shooting line designed to offer all the benefits of mono, with better handling, less memory, and superior shooting performance.
With its uniquely oval profile, this line builds upon the success of our legendary Lazar Line while delivering improved torsional strength, twist resistance, and knot stability. Whether you’re trout spey casting or swinging for big steelhead and salmon, the OPST Oval Line gives you the edge in distance, control, and feel.
Key Benefits
Oval Profile for Reduced Twist
The oval shape adds torsional rigidity, reducing line twist and improving flow through the guides — especially the first stripping guide.
Low Memory, High Performance
Softer and more supple than standard mono, the Oval Line resists coiling and lays out beautifully for smoother handling.
Minimal Drag, Maximum Shootability
The streamlined shape reduces friction and enhances your ability to shoot line effortlessly, even in windy or wet conditions.
Knot Strength You Can Trust
Engineered with high-grade mono construction, the Oval Line delivers strong, reliable knots that hold under pressure.
