Sink Tip Fly Lines Quick Picks
Best Entry-Level Sink Tip: Scientific Anglers Frequency Sink Tip Type III Fly Line - A 10ft Type III tip on a floating running line gets streamers into the column without the cost of a full sinking system, a good first sink tip for trout and smallmouth water.
Best for Deep Streamer Runs: Scientific Anglers Sonar Titan Sink Tip Type 6 Fly Line - Sinking at 5.5-6.5 ips, this line punches big streamers into the deep buckets and ledges where the biggest fish in a run tend to hold.
Best for Striped Bass: Rio Striper Premier 30ft Sink Tip - A density-compensated 30ft head keeps flies swimming level through the retrieve, exactly what you want when stripers key on baitfish holding at depth.
Best for Tarpon & Tropical Bluewater: Rio Elite Leviathan 26ft Sink Tip - A short, heavy head loads big bluewater rods, and a hard tropical coating won't go soft in the heat, built for the largest tropical species.
Best Replacement Tips for Skagit/VersiTip Rigs: Rio InTouch 15ft Sink Tip Replacement Tips - Low-stretch construction and color-coded loops let you swap sink rates on the water instead of carrying a second spool.
How to Choose a Sink Tip Fly Line
Sink Rate
Type III (2.5-4.0 ips): A moderate rate that's easy to cast and mend, Type III tips like the Scientific Anglers Frequency Sink Tip Type III cover most river streamer situations without fighting bottom.
Type VI and faster: Sinking 5.5+ ips, lines like the Sonar Titan Sink Tip Type 6 get down fast in deep or heavy current where a slower tip never reaches the strike zone.
Integrated Line vs. Replacement Tips
Integrated sink tip line: A full line like the Rio Premier 24ft Sink Tip pairs a fixed sinking section with a floating body, simplest to fish straight off the spool.
Interchangeable tip system: Replacement tips such as the Rio InTouch 10ft Sink Tips let you loop different sink rates onto one running line, covering water from riffles to deep pools.
Length of the Sink Tip
Shorter tips (10ft): Easier to cast and mend on smaller rivers, a 10ft tip like the Cortland Classic 444 keeps more floating line on the water for control.
Longer heads (24-30ft): Longer heads found on lines like the Rio Striper Premier and Rio Elite Leviathan get flies deeper and hold depth longer through a swing, suited to open water and bigger rods.
On-the-Water Tips
Match grain weight to your rod: Sink tip and Skagit-style lines are graded by grain weight, so check your rod's recommended grain window before buying.
Use a loop-to-loop connection: Interchangeable tips rely on clean loop-to-loop connections; keep loops trimmed and free of fraying.
Mend less, not more: Sink tips fish best with minimal mending. Let the sinking section do the work instead of stack-mending against it.
Rinse after saltwater trips: Coatings and cores last longer with a fresh water rinse after every outing.

Sink Tip Fly Lines FAQs
Q: What sink rate do I need for streamer fishing?
A: For most river trout and bass water, a Type III tip in the 2.5-4.0 ips range gets flies into the zone without hanging up on bottom. Move to a Type VI or faster tip for deep pools, heavy current, or a short swing.
Q: Should I buy a full sink tip line or replacement tips?
A: If you mostly fish one type of water, an integrated line like the Cortland Classic 444 is simpler and cheaper. If conditions vary trip to trip, replacement tips let you change sink rates using one running line.
Q: Can I use a sink tip line on a single-hand rod?
A: Yes. Compact sinking tips like the OPST Commando Sink Tips are built to bring spey-style, single-hand presentations to trout, sea-run cutthroat, and smallmouth bass in both fresh and salt water.
