Stren Sonic Braid is the VERY latest in Braided Fishing Line Technology. If you were a big fan of Super Braid, you will ABSOLUTELY LOVE SONIC BRAID. Sonic Braid is a ROUND, full-bodied braid that resists wind knots, and has unmatched knot strength for long lasting dependability. Made with all GLIDECOAT TECHNOLOGY, this super-smooth, faster/farther casting braided line lasts longer, and holds its color far better than the other line companies trying to compete for the top spot. Stren Sonic Braid has clearly left all wanna-be competitors in the dust!
