Daiwa JBraid Grand 30lb Braid

Daiwa’s premium braid goes to another level with the J-Braid Grand. A premium 8-strand PE, J-Braid Grand is made from an advanced raw material (IZANAS) and uses a technologically advanced construction method. J-Braid Grand is J-Braid’s strongest, most abrasion resistant line ever. Four times more abrasion resistant than other braided lines, J-Braid Grand has a best-in-class short pitch fibre construction that significantly reduces line damage and failure to dramatically increase abrasion resistance and straight-line pulling strength. A short pitch construction also aids in creating an even rounder profile for optimum line performance. Rounder profile braids tangle less and perform better, making J-Braid Grand our best performing J-Braid ever.

Made in Japan and available in sizes ranging from 6lb (0.6PE) to 120lb (PE12) in high-visibility island blue & depth-marked multicolour. J-Braid Grand is the smoothest and best performing J-Braid we’ve ever made.

Key Statistics

Measured Diameter: .374mm (+133.5% on claimed .28mm)
Measured Breaking Strain: 49.53lbs (+165% on claimed 30lbs)
Abrasion Breaking Strain: 14.96lbs (30.2% of measured)
Both Diameter and Breaking strain indicate that this is closer to a 50lb line, not 30lb. Abrasion resistance is slightly below average compared to others.
