Quick take

A 9-weight saltwater fly line with low-stretch core designed for average and novice fly fishers targeting bonefish, permit and tarpon.

The RIO Mainstream Saltwater is a blue floating fly line in a 9-weight, made for anglers fishing saltwater species such as bonefish, permit and tarpon. Its slightly heavier, shorter head suits average and novice fly fishers who want a line that turns over larger, wind-resistant flies. Each saltwater line carries a hard coating and a low-stretch core for steady handling on the water.

Best for

  • Saltwater flats fishing for bonefish and permit
  • Small boat or wading trips where distance is moderate
  • Fly fishers new to saltwater or intermediate in skill

Skip if

  • You fish deep offshore water; use heavier weights
  • You need to punch into strong wind

Strengths

  • DirectCore stretches 30 percent less than standard tropical cores for better feel
  • Slightly heavier weight and shorter head help novice casters load a rod
  • Lies straight on the water with minimal coiling

Trade-offs

  • 9-weight may be too heavy for small tarpon or light permit
  • Line coils can persist in tropical heat even with low-stretch core
  • Designed for average conditions; not optimized for extreme distance
