The rigging accommodates a variety of trailer hook styles to match the fish you're after. TrollTrue's 60 lb rigging comes standard with 4X strong treble hooks and is the recommended setup for drags up to 30 lbs — in 90% of fishing situations, this is what anglers should be running. For larger fish like tuna and marlin, TrollTrue offers 100 lb rigging, which comes standard with an 8/0 J-hook as the trailer hook. Optional trailer hook styles include treble, J-hook, and circle hook in various sizes, and all work fine with TrollTrue lures. Regardless of which trailer hook style you choose, the hook is meant to swim freely alongside the bait as it trolls — not be embedded in the baitfish itself.
