Sink Tips for Spey Rods: T vs Type, Sink Rates, Lengths & Efficiency

Sink tips are one of the most misunderstood—and most important—parts of a spey system. In this technical episode, we break down sink tips for spey rods and explain how to fish them more efficiently.

We cover the key differences between “T” material tips and traditional “Type” tips, how sink rates change with different tip lengths, and why faster sinking doesn’t always mean better depth or presentation. We also talk through the tips we personally prefer, when we choose them, and how those choices lead to more consistent, efficient fishing.

This episode is geared toward anglers who want to understand why their system works—not just copy a setup.

In this episode:

T tips vs Type tips: density, construction, and performance

Sink rates explained (IPS vs real-world depth)

How tip length affects swing speed and fly depth

Matching sink tips to water type, flow, and rod
