One vote for 6-12'' suckers, amazing how even a 2-3 pound pike will hammer one. My biggest ice fishing pike is a mere 12lbs though so i may be off by a bit, i have caught a ton of pike in the 7-10 pound class using this method however. The biggest pike i've ever seen landed was caught on a anchoive, Just broke the 35 pound mark and was pulled out of 4 feet of water.
