This is kind of a silly question . If it's a tourney it ok? I weigh them all. its' part of my fun. My weight and logs are all part of my own game . Lots of PB's to break when targeting big fish too. If you chose to target big fish. I take videos and one of the most common questions is "how big" . But if I weigh a few that go 4 to 6 lbs and set them free within 30 min where I caught them, Why is it OK to hold them all day in a well and put them in a bag, then put them in a basket , weigh them , put them back in a tank or your live well and let them go in a place far from home in the name of Gambling? I think weighing fish is not a problem at all as long as you take care of the catch. I think tourney or not most of us take good care of the catch. : ) Have fun!
