This line performs well in cool freshwater conditions. The slow sink rate keeps the flies just below the surface, which is perfect for targeting big bass and pike. The turnover is quick and the welded loops stay secure during casting. I’ve used it in temperate lakes and it’s proven reliable.

Great for fishing larger flies in still waters. The intermediate sink rate works well for musky and big bass. A bit heavier than standard lines, but the performance justifies the weight. The AST coating holds up well in water exposure.
Maria Murray –
Fished in a cold water lake with Atlantic salmon. The line stayed intact and delivered consistent results. The sink rate is just right for getting flies to the desired depth. Easy to tie and casts smoothly.
