Hi Mossie,
A net is best. If you go to the Lip Grips, be careful which one you use. Boga Grips are the best. Most of the cheaper imitations that we all use have a bad fault when it comes to trying to land big fish with the. If the fish pushes forward, the jaws on the grip will open. Try your's in the palm of your had. Just push down on the jaws. Don't lift barra into the boat by the jaw either. They are not designed to carry their body weight by the jaw, and the fish will probably die. If you use the grips, support the body with your other hand. Not an easy feat with a large barra in the water at the side of the boat.
