They have been very segregated for me this year. I have found crappie several times in a 20 yard area all to themselves with brim on both sides, but only crappie in that 20 yard area. No mix of brim/crappie, just crappie in most small areas I've found. And some times a lot of crappie, we're talking limiting out in 2 hours, in these small areas. But you cast outside the zone, it's bull brim.
