Live in Grand Forks and have been to Devils 5 times so far this winter. Buckshots and flutter spoons have been solid for us so far for walleyes. I’d recommend gold or UV green for the color. Have also had some success on size 4 UV green rippin raps for eyes. Make sure to make use of your 4 lines as well by throwing out tip ups and using dead lines. Gold tungstens with wax worms and small gold buckshots with waxies or a small minnow head have been working for perch. In terms of line, I find that 8lb braid or mono (depending on if your inside or outside) to a 6 lb fluoro leader is more than enough to handle bigger fish out of that lake.
