there are a few small differences between high and low finners ive noticed over time, natives are much more prone to hit hardware, and they respond to the tide more.. they also seem to get further up the river faster. the color green in the winter is a buck native favorite and they also respond to natural earth tones, green, black, bronze better than frankenfish. when I fish beads later in the spring my catch rate of natives goes through the roof, and simply by switching to an orange or peach glo bug can turn it into a hatchery show. There is not really any science to what im saying but I have kept records for 9 years on what and where and water temp at time of capture and these are the differences that pop out, so this is all my own opinion.
