This sink tip performs well in clear water. The triangle taper gives a smooth cast and the flies sink quickly without swinging too much. I’ve used it with a 4 IPS line and it’s easy to control during fishing.

The sink tip is reliable and doesn’t have the hinge issue found in other models. It casts cleanly and keeps the line stable. The grey and ivory color makes it easy to see in the water.

I’ve been using this for several weeks on trout streams. It sinks fast and maintains a steady depth. The taper design helps with turnover and makes it easier to adjust depth.
