Toothy fish are a blast to catch on the fly rod. At any moment, they can snap your line and be gone for good. Having a strong and trustworthy wire tippet or bite wire is extremely important.
You work hard to find the fish and get your fly in front of them only to loose them mid-way through your fight because the fish chewed through your tippet. Using a high poundage of tippet works sometimes but eventually a toothy fish will chew through. A piece of monofilament tippet will only last so long.
What you need is a strong and durable bite wire.
As for wire tippet, try RIO Powerflex Wire Bite Tippet. RIO and Scientific Angler make solid leaders for toothy fish with Scientific Anglers Predator Leader and RIO Toothy Critters Tapered Leaders.
Incorporating a wire bite tippet in your fly fishing rig when targeting toothy fish will greatly improve your success rate.
You may occasionally loose a fish or two when using a bite wire but that is far better than only landing one or two when using a heavy poundage of monofilament.
Bite wires have another advantage, durability. What I mean by this is that bite wires will last through multiple fish while you’re lucky when you landing one fish with monofilament.
Up your toothy fish success rate with a wire tippet.
