All I can think of, is pike don't school , they will all be attracted to similar structure and whatnot so where there is one there will most likely be others in the vicinity, but that might mean out of sight of your presentation. Although walleye do school, I have read that they spread out quite a bit, so similarly to pike, there are most likely others in the area, just not right at that hole. Neither of these fish are like small bass which seem to come barreling through in larger schools, out of that school your going to have a certain percentage that are hungry and you're going to get a few flags in the area. Some people might tell you to be happy you're getting ONE flag during a day of pike fishing, lol. I'm not sold on the idea of no noise , etc. (when fishing pike or bass, I'm not too familiar with walleye) I've had some of my most productive days during derby's and on large lakes where trucks, quads, sleds and everything else under the sun were whizzing by and I've had horrible days where it was just me and one other person in sight sitting quietly 1/4 mile away from our traps. Also a lot of hits seem to come as you are checking and moving bait around. I just think if your in the right area and fish are hungry and you have the right presentation they will bite, if not, they won't. To each their own... I have no scientific proof of anything, just letting you know my own experiences. Good luck this year..
