Yep, got to try numerous plastics till you find the one that works. It's part of the fun!

When water is stained, you notice the fish have less color and tend to be pale looking. The bait fish are the same way. I was fishing fairly stained water one day in late May (visibility about 5") and crappie were biting. Since the fish looked very pale, I decided to switch to a white curly tail on a white jig head. The crappie hammered that bait. I learned a lesson that day by experimenting.
