Your're dead on CK14. I'll either move out deeper or switch to a bigger bait and fish deeper. The 2" crappie jigs are killer for the bigger perch. Also, a 3inch grub will always catch the bigger perch. The big ones seem to roam on their own. They only time of year I have found schools of big perch is early in the fall in water that's at least 20' feet and has a rocky bottom.
