Fly Line Backing

 Fly Line Backing in-stock, no sales tax - $50 orders ship free in USA.

Possibly the most advanced braided fly line backing available for most applications. TUF LINE is braided from super strong "Gel-Spun" Spectra fibers, TUF LINE XP is incredibly smaller in diameter than equal strength backing braided from Dacron yet is supple and without stretch.  XP is braided with a new aerospace technology called "Tension Lock" for even smaller diameter, smoothness and abrasion resistance.  Thirty pound test XP is .011 in diameter. That is the same about the same diameter as 8-pound test Maxima Chameleon tippet material.  Add another .001 and the strength nearly doubles to 50-pound test.  That is the approximate diameter of 10-pound test Maxima.  This small diameter increases the backing capacity of every fly reel and reduces backing drag in the water.  XP lays down very smooth.  There doesn't seem to be any tendency for XP to cut down into itself or case reel spool breakage even when 500 yards are loaded onto a spool.  Thirty pound XP is half the diameter of 30-pound Micron.  Fifty pound XP is about 2/3 the diameter of 30-pound Micron.  

You can get more TUF LINE XP on your reel spool. TUF LINE XP is very abrasion resistant, U.V. resistant and has very low stretch. Bright yellow color.
