I use these leaders for trout fishing in streams. The 2.5 sink rate works well for reaching deeper pools without changing my fly line. The micro-swivel keeps the line from twisting, and the welded loop attaches quickly. Very reliable in the field.
Ruth Fraser –
Great for adjusting depth on the fly. I switched from traditional sinking lines and noticed better control. The 4.0 sink rate helped me catch fish in deeper water. A little longer than expected, but still fits my setup.

Used them on a cold spring trip. The leaders stayed intact through windy conditions. The 1.5 sink rate worked perfectly for shallow runs. Easy to attach and perform consistently.
