ive caught pike on just about everything going. ive caught them jigging a plain spoon, live bait(dace and large suckers), jighead with a minnow, tube jigs, etc etc. i find its all on how aggressive they are. i'd set a still line(tip up) with live bait and try various spoons and jigs and vary speeds and jigging patterns tillyou start laying into them. it might take some trial and error.
