GTs break 10-weights for breakfast and run straight for the reef when they're hooked, breaking your fly line on knife-sharp coral. The only chance you have is to hit 'em and hold 'em. The typical 20- or 30-pound core isn't going to work. That's why Airflo developed the Ridge GT, which features a 50-pound braided core. The lines feature a tough, tropical coating and ridges running the length of the line to prevent tangles and offer lower friction in the guides. Those casts that weren't even in the same zip code now reach out and touch someone.
