Edward Lyman –
Used this line for bonefish and tarpon in coastal areas. The drag reduction made a noticeable difference in casting accuracy and sensitivity. It handled wind well and stayed intact even after multiple casts.
Boris Black –
Fished with this line during a permit season. The durability exceeded expectations. No breaks or fraying after several hours of use in rough conditions. Highly recommend for serious fly fishing.
Dominic Alsop –
Good performance in light to moderate wind. The head is strong and responsive. A bit more expensive than standard lines, but the performance justifies the cost for serious anglers.
