I found and tried to fish some large schools of shad and had weak results. I moved to the next tree down the creekbed and commenced to loading up. Fishing in them was tough, fishing near them was great. When I trolled cranks as G spoke of, I could almost countdown to the strike when my baits went through a school of shad, there was always some fish mixed in or under or around them and they liked my cranks. I think it was because while they were close in size they acted different. Whatever the reason, it’s working. Keep after it, you’re doing something right.
