Pike aren't my primary fish to chase during the winter but do it enough in the winter to have experimented some. Last winter seemed to do better with red hooks and as a twist, made some quick strike rigs using bleeding wire (red) with the red hooks when making them up and did very well. Generally a dead bait user and anything that makes it look more vulnerable/dying/hurt will rarely hurt. If they're hungry or aggressive not sure it matters, pushing them over the edge when a bit picky, maybe, makes me feel better though
