Scientific Anglers MPX Wavelength Fly Line


The SA Wavelength MPX Taper combines the famous casting qualities of the old GPX with a longer rear taper for superior loop control, roll casting and line mending.  The MPX is now our favorite all-purpose trout line for fast and medium-fast action fly rods. 

Scientific Angler Wavelength MPX lines feature the Scientific Anglers proprietary textured coating, which provides maximum shootability without the abrasive qualities of Sharkskin lines.  This fantastic taper is designed to make accurate presentations at all distances and any type of fly.  Dry Tip technology is applied to the front six feet of the line for excellent floatation.
