The RIO Mainstream Sink Tip is a stellar introductory sink tip line for the average fly fisherman. The shorter front taper facilitates tight casting loops and positive turnover as well as utilizing a thicker belly to aid in turning the heavy twelve foot sink tip.

Features:

• Shorter head configuration for positive loading and shooting of line
• Thicker floating belly to help turn over the heavier 12 ft sink tip
• Supple coating that remains memory-free in cold water
