Winston BIIx 13'3" #7/8 line recommendations
The 13'3" Winston BIIx #7/8 is the default rod shown in the Line Finder. The Scientific Anglers chart lists a 450 grain Scandi and 510 grain Skagit reference for this model. Those numbers describe different line styles, so compare each with the appropriate head rather than treating them as interchangeable.
Starting points by line style
| Style | Line or reference | Size | How to use it |
|---|---|---|---|
| Scandi | Scientific Anglers chart | 450 gr | Chart reference for a lighter presentation. |
| Hybrid | Airflo Rage Compact | 450 or 480 gr | Rod-specific candidates; compare both to find your preferred load. |
| Skagit | Scientific Anglers chart | 510 gr | Starting head target; match a compatible tip and fly. |
Comparing the two Rage sizes
A side-by-side test is more useful than assuming one grain number fits every caster. Keep the same rod, running line, fly, and leader or tip while trying the 450 and 480 grain heads. Notice whether the anchor holds without feeling sticky, whether the D-loop forms with the room you have, and whether turnover remains controlled. Change one part of the setup at a time so the comparison means something.
The Rage Compact sits between typical Scandi and Skagit presentations. Start with 450 grains if you want to compare a lighter load, and test 480 grains when a fuller load suits your tempo or setup. The final choice depends on leader or tip and fly as well as the rod. The finder also shows current catalog candidates and longer-line options.
These recommendations are only a starting point. Open the Spey Line Finder to compare the other line styles and candidate sizes for this rod.
