Its a long time since I whacked a fish on the head. If I go out with that goal in mind I still have a couple of priests from my salmon fishing days. One of them probably still has a scale or two attached and might be up to the job of dispatching a keeper.
Last year I told myself that I would take a keeper for the pot but I was always a long way from home without an ice box nearby so they all went back to fight another day.
This year maybe. I tell mysef I keep my options open. When the time is right I'll take one to eat and a whack on the head is a very effective way to dispatch a fish if you know what you're doing! Big fish are not easy to kill. The blue water guys have a version of a priest that looks about the size of a baseball bat.
When sight fishing, look over your shoulder from time to time, you never know who's behind you
