Spider rigging works anytime. If you don't have a lot of time to fish and want to get fish in the boat quick there's no better way. Rigging the pre-spawn staging areas and flats are really good and if you want total chaos, run them along the banks in spawning coves. Usually run the closest pole to the bank about a foot deep and add a foot on each rod as they get deeper. Also helps a lot to get an extended reach net. Takes a little time to get them in the water but well worth it.
