I’ve used the Sink 25 in cold streams and it gets my flies to depth much faster than regular lines. The sinking head works well with my streamer rig and the handling section feels solid. Casts are smooth and I notice less tangle during windy conditions.

Great for deep water fishing in winter. The 200 grain version works well with my 6-7 weight setup. It sinks quickly and stays on course. A bit stiffer than other lines, but that’s expected for a sinking line.

Used it in a cold mountain stream and the flies reached the bottom in under 10 seconds. The line feels durable and the low tangle design made casting easier, especially when I was fishing from a moving boat.
