I often replace factory standard hooks after they have had some time and action in the water. Most of the fish I target don't mangle gear, but having said that on one or two occasions I have seen a few of my trebles and lures mangled by jacks. I see the value in better hooks and i carry spares and split rings in my tackle box. But replacing them straight out of the packet, now I feel like i being wasteful.
Also, can anyone tell me if they flatten out the barbs on their trebles for fish conservation and safety? I am warming to the idea. After having put a treble through my thumb i see value in flattening them, do you?
