GLX is still one of the lightest, most sensitive high performance rods that G.Loomis makes. It is noticeably lighter and more sensitive than their IMX and all the other lower modulus materials they use. It has been the cornerstone of their product line for over 20 years. Its high modulus and high tensile-strength allow them to use as much as 15% less material than a comparable IMX rod creating a very dramatic reduction in weight and maintaining the same power. They have totally redesigned the GLX Series, using a new proprietary reel seat, split-grip handle configuration and Fuji K-frame SIC guides. The Mag Bass and Spin Jig rods in the classic actions feature full cork grips. Some of the tapers are new as well, improving the rod line across the board. The new GLX has increased sensitivity if you can imagine that! All we can say is... they're amazing!
