Rio Tropical DirectCore Flats Pro Fly Line - Closeout
“Best New Fly Line for 2018” at the European trade show “EFTTEX”, and “Best New Saltwater Fly Line for 2018” at the US trade show “IFTD"
Low stretch performance is perfect for bones, perms and poons. Each line is built with a front taper that loads easily at close range, and with a mid-length head and extended back taper that provides stability for fast, accurate, long-distance casts.
Features of the DirectCore Flats Pro Fly Line:
- Easy annealing, low-memory core that lays perfectly straight on the water
- Low-Stretch "DirectCore" for hard, solid strip sets
- Mid length head & long rear taper for complete line control
- High floating running line that will not sink and impede the cast
RIO’s new flagship saltwater fly line has been designed for anglers hitting tropical flats in search of bonefish, permit and tarpon. The line is built on RIO’s new DirectCore, a proprietary low-memory, low-stretch monofilament core that retains its stiffness in tropical heat, yet lies straight on the water without curl or retraction. The core, which has 30% less stretch than regular tropical saltwater fly lines, ensures solid strip sets and shortened fight times.
In addition to a new Core, RIO’s SureFire technology was added to the Flats Pro line. This triple color, distance-marking design takes the guesswork out of accuracy and distance control, allowing anglers to make higher percentage shots to cruising targets.
The DirectCore Flats Pro line is available in floating models and a clear tip “StealthTip” option that features a full-float head with six feet of clear intermediate at the tip. This nearly invisible front section allows for shorter leaders and easier, more accurate casts, while the increased density provides greater wind penetration.

Good line - even for cold water
I bought this line in a WF10F for striper fishing. I’ve been using the WF8 15’ intermediate tip flats pro line on my Salt HD for the last couple of years, and I just love the taper. I bought the WF10F line for my Igniter and I am not disappointed. Rio striper lines work great for casting large flies, but the presentation of a small sand eel or a tiny gurgler suffers due to the short aggressive tapers. I have to stretch the line good before casting as it is a tropical line, but I have no issue shooting the entire line out of the rod tip. If you’re a Rio guy and you are in the market for a longer tapered line for inshore species, this one is a good option.
