What worked for you during the pre-spawn?
....everything I use all year as far as lures go - mostly soft plastics on light jigs/ braid with 6# test fluorocarbon.
We're at prespawn temps and the pads haven't gotten big enough (a signal when the spawn will begin). I've been catching them about 30-40 yds. and parallel to shorelines but not all shorelines. Deep bottom weeds are growing fast so open areas are the easiest to fish for suspended fish. 4 species have been hitting in water that is around 55 degrees which in some state triggers crappie to spawn.
