When the game is striped bass, cobia, or large grouper and snapper, don't bring a net that's sized for largemouth bass; bigger is always better when you're selecting a landing net. And as I mentioned, it's imperative to slip the net in front of and underneath the fish, forcing it to swim into the mesh as you lift, providing the angler lowers the rod as he should. Trying to net fish tail first, or even belly first, is a losing proposition, as the fish can panic and swim out of the net.
With long leaders, like those used for billfish, sharks, dolphin and wahoo, two vital things merit attention. Most notably, never take possession of the leader by wrapping it around your hands, no matter how many pairs of gloves you have on. If you do and a large, powerful fish surges or charges off, you risk serious injury or, worse, being pulled overboard.
