Generally, while watching my flasher, I keep my jig above the fish and tease them up off the bottom or if they are suspended slightly above them until they can't stand it and come up to check it out and hit. I like to jig aggressively to get them excited off the bottom but as they approach I generally slow down somewhat and keep jigging tiny hops while raising them even more. That way, I can tease other fish off the bottom and the first one usually hits due to competition of the other ones. Also, I learn the fishes limits as to how high off the bottom they will go before returning to the bottom if they don't hit.
Other times, I get them up off the bottom but they don't chase, so I slowly do tiny hops while lowering it to just above them and sometimes get hits that way. Another way is if fish leave the cone in a good hole, and if the jig is heavy enough, I pound it on the bottom and jig aggressively stirring up daphnia. Often this attracts fish and ultimately to my jig.
In all, I try to get my ice jig to resemble a copepod or daphnia type movement to entice strikes.
Anyone else have some thoughts or ideas?
