When I fish a tournament, I weigh each fish as I catch them, attach my cull ropes (home made) and, upon my sixth keeper, cull my smallest fish by weight. I thought everybody did it that way until I heard some guys talking at a bait shop recently. This one guy said, as long as he is in a "good spot" (or they are biting well) he may have multiple keepers in his live well at a time, then cull maybe once or twice in a tournament. It got me thinking that, on tv, you never see the pros weigh any fish while in their boat... I often see them measure, but have never seen one weigh or use a balance beam. any thoughts?
