I’ve used this line for several seasons on my bamboo rod. It casts smoothly and stays intact even in cold weather. The dry fly presentations are very natural and the line doesn’t tangle easily. Great for small, delicate flies.

The AST Plus coating makes a noticeable difference in how far and straight the line shoots. I’ve tried several other lines, but this one consistently performs better in windy conditions.
Rebecca Lewis –
Works well for small nymphs and dry flies. A bit more expensive than standard lines, but the performance justifies the price for serious fly fishing in cooler climates.
