The pull strength of the new Ocea 8 400 metre brain line is improved up to 25 per cent greater than the previous EX8 for the same diameter. Ocea 8 utilises Shimano's exclusive Tough Cross braiding method. What makes it stand out from the rest is that the line is woven at 45 degrees under tension to create a tighter fibre structure, making it more stable, easier to manage and possesses increased abrasion resistance. Shimano Heat Sink coating has been developed and applied to the line to reduce concentration of heat from guide and drag pressure on the line. The Izanas fibre has a new and improved fibre lay technology exclusive to Shimano, which prevents flattening of the line that could lead to premature breakage. As a result the pull strength and abrasion resistance is vastly improved.
