The sink-tip section sinks at 7.75 inches per second - it gets down where it needs to go and stays there. This custom tip line is capable of achieving 7 through 15wt rod sizes - a super sweet line for those looking to get precise. Check out the chart to help guide you to the right custom cut length.
- Cut-to-fit design lets you cut the tip to the ideal weight for your fly rod
- Goes deep and stays deep
- Intermediate running line
- Sink Rate: 7.75 ips
