When use a sink tip instead of full sinking line?

How do I choose the right sink tip type?

Match the type (I–V) to depth, fly size, current speed, and target species.

How do I rig a sink tip setup?

Connect tip to floating line, add leader and fly; ensure clean transition and correct length.

What situations call for a sink tip?

Deep-holding trout or steelhead, lake bottoms, and saltwater flats when fish are below the surface.

Product Description

The RIO MDC Sink Tips are designed to give anglers ultimate control and precision when swinging flies on the river.

Built with a progressive density design, these sink tips descend faster near the fly, ensuring your presentation reaches the strike zone quickly while maintaining the smoothest possible turnover for effortless casting.

Available in 12-foot and 18-foot lengths, the MDC Sink Tips match a wide range of rod setups and fishing conditions. Three color-coded rear loops—white (#5/6), blue (#7/8), and gray (#9+)—make it easy to identify the right tip for your Scandi Body or shooting head system. For added versatility, RIO also offers a clear intermediate option in both H/I and F/H/I sink rates, giving you precise depth control no matter the water conditions.

Whether you’re chasing steelhead, salmon, or trout in fast or slow water, the RIO MDC Sink Tips deliver unmatched line control, smooth energy transfer, and accurate depth presentation for optimized swing performance.
