YGK Castman ’Blue Special′ : PE2.5

YGK Castman 'Blue Special′ : PE2.5 Braid

Adjusted for near-shore casting

Ultra raw yarn has been brushed up to become WX8, which has extremely excellent high strength and durability properties!

Targeting worthy opponents in shore and offshore casting, such as yellowtail, horse mackerel, horse mackerel, and bonito, this line is fully tuned for casting, using the WX method, which reinforces the super-strong UJ thread with a super special resin coating and a setting that enhances linearity. This
high-power, high-quality Izanas line has the potential to cover even mid-class monsters, such as yellowtail over 10kg and tuna in the 30kg class.

Summary

- Measured Ave Diameter: 0.322mm (no claimed diameter)
- Out of Roundness: 0.068mm (21.12% variation in diameter)
- Measured Maximum Break: 46.24 lbs (100.52% of claimed 46 lbs)
- Measured Stretch @ Break: 2.92%
- Abrasion Maximum Break: 15.74 lbs (34.04% of max break)
- FG Knot Maximum Break: 35.24 lbs (76.21% of max break)

A great result for this line by YGK. We tested the break at only 0.52% above it’s quoted strength which shows it is extremely accurately rated. Consistency was also exceptional, with only 0.38lbs difference between all break tests.
