Up until they introduced NRX, GLX was the highest performance graphite system G.Loomis ever used. Its high modulus and high tensile-strength allowed them to use as much as 15% less material than a comparable IMX rod. It doesn't take a mathematician to figure out they’re getting a lot lighter here. Because the GLX fibers were even stiffer than IMX, everyone enjoyed the sensitivity and the reduction in overall rod weight. The material has a higher modulus than IMX and the rods are noticeably lighter and more sensitive then IMX, GL3, their fiber-blends and now E6X. Their new GLX continues that legacy of extreme performance and light weight! This year they have totally redesigned the GLX Series, using a new proprietary reel seat, split-grip handle configuration and Fuji K-frame SIC guides.
