Making sure you are using quality terminal tackle is the fishing equivalent of "dotting your i's and crossing your t's. Your setup is only as strong or capable as your weakest link. Thankfully, now more than ever, high quailty terminal tackle is available at competitive costs. Spro, Rasco, Breakaway, Tactical Anglers, Owner and many other companies stake their reputation (and your success) on the quailty of their terminal tackle.
Fishing is all about connections. You've put a lot into your rod and reel, so quality terminal tackle is just as important when landing the fish you've been searching for.
