What makes Infinity Plus different

• Smooth amplitude coating enables long, effortless casts with consistent freshwater performance
• Weight-forward taper delivers tight loops and easy line control for both short and long casts

Real-world use cases

In the field, anglers report that the Infinity Plus can bomb out streamers while maintaining finesse when presenting dry flies. The long head and front taper help with mends and line control, enabling smooth line management at a variety of distances. The colorway—Mist Green with Buckskin and Willow tones—helps the line blend with water and shoreline in many freshwater environments.

Designed for a broad range of freshwater fishing, it may suit trout and panfish as well as larger targets like pike or steelhead in certain setups. The Infinity Plus aims to offer a balance between distance, accuracy, and delicacy without claiming guaranteed results, inviting you to test how it complements your preferred tactics and rods.
